+ *
+ * Theory of operations
+ * ====================
+ *
+ * Clock scaling can be used to lower the power consumption of the CPU
+ * core. This will give you a somewhat longer running time.
+ *
+ * The SA-1100 has a single register to change the core clock speed:
+ *
+ *   PPCR      0x90020014    PLL config
+ *
+ * However, the DRAM timings are closely related to the core clock
+ * speed, so we need to change these, too. The used registers are:
+ *
+ *   MDCNFG    0xA0000000    DRAM config
+ *   MDCAS0    0xA0000004    Access waveform
+ *   MDCAS1    0xA0000008    Access waveform
+ *   MDCAS2    0xA000000C    Access waveform
+ *
+ * Care must be taken to change the DRAM parameters the correct way,
+ * because otherwise the DRAM becomes unusable and the kernel will
+ * crash.
+ *
+ * The simple solution to avoid a kernel crash is to put the actual
+ * clock change in ROM and jump to that code from the kernel. The main
+ * disadvantage is that the ROM has to be modified, which is not
+ * possible on all SA-1100 platforms. Another disadvantage is that
+ * jumping to ROM makes clock switching unnecessary complicated.
+ *
+ * The idea behind this driver is that the memory configuration can be
+ * changed while running from DRAM (even with interrupts turned on!)
+ * as long as all re-configuration steps yield a valid DRAM
+ * configuration. The advantages are clear: it will run on all SA-1100
+ * platforms, and the code is very simple.
+ *
+ * If you really want to understand what is going on in
+ * sa1100_update_dram_timings(), you'll have to read sections 8.2,
+ * 9.5.7.3, and 10.2 from the "Intel StrongARM SA-1100 Microprocessor
+ * Developers Manual" (available for free from Intel).

+ * to perform this job, hence the use of a deferred delay.
+ *
+ * A deferred delay for thermal monitor is considered safe because:
+ * If the chip gets too hot during a sleep state it's most likely due to
+ * external factors, such as the surrounding temperature. I.e. no SW decisions
+ * will make any difference.

+ *	https://groups.google.com/forum/#!topic/ultra-cheap-sdr/Y3rBEOFtHug
+ *	https://github.com/n1gp/gr-baz
+ *
+ * From what I understood from the threads, the original driver was converted
+ * to userspace from a Realtek tree. I couldn't find the original tree.
+ * However, the original driver look awkward on my eyes. So, I decided to
+ * write a new version from it from the scratch, while trying to reproduce
+ * everything found there.
+ *
+ * TODO:
+ *	After locking, the original driver seems to have some routines to
+ *		improve reception. This was not implemented here yet.
+ *
+ *	RF Gain set/get is not implemented.

+/*
+ * The stk webcam laptop module is mounted upside down in some laptops :(
+ *
+ * Some background information (thanks to Hans de Goede for providing this):
+ *
+ * 1) Once upon a time the stkwebcam driver was written
+ *
+ * 2) The webcam in question was used mostly in Asus laptop models, including
+ * the laptop of the original author of the driver, and in these models, in
+ * typical Asus fashion (see the long long list for uvc cams inside v4l-utils),
+ * they mounted the webcam-module the wrong way up. So the hflip and vflip
+ * module options were given a default value of 1 (the correct value for
+ * upside down mounted models)
+ *
+ * 3) Years later I got a bug report from a user with a laptop with stkwebcam,
+ * where the module was actually mounted the right way up, and thus showed
+ * upside down under Linux. So now I was facing the choice of 2 options:
+ *
+ * a) Add a not-upside-down list to stkwebcam, which overrules the default.
+ *
+ * b) Do it like all the other drivers do, and make the default right for
+ *    cams mounted the proper way and add an upside-down model list, with
+ *    models where we need to flip-by-default.
+ *
+ * Despite knowing that going b) would cause a period of pain where we were
+ * building the table I opted to go for option b), since a) is just too ugly,
+ * and worse different from how every other driver does it leading to
+ * confusion in the long run. This change was made in kernel 3.6.
+ *
+ * So for any user report about upside-down images since kernel 3.6 ask them
+ * to provide the output of 'sudo dmidecode' so the laptop can be added in
+ * the table below.

+	 * Workaround for errata i743 - LPDDR2 Power-Down State is Not

+	 *
+	 * i743 DESCRIPTION:
+	 * The EMIF supports power-down state for low power. The EMIF
+	 * automatically puts the SDRAM into power-down after the memory is
+	 * not accessed for a defined number of cycles and the
+	 * EMIF_PWR_MGMT_CTRL[10:8] REG_LP_MODE bit field is set to 0x4.
+	 * As the EMIF supports automatic output impedance calibration, a ZQ
+	 * calibration long command is issued every time it exits active
+	 * power-down and precharge power-down modes. The EMIF waits and
+	 * blocks any other command during this calibration.
+	 * The EMIF does not allow selective disabling of ZQ calibration upon
+	 * exit of power-down mode. Due to very short periods of power-down
+	 * cycles, ZQ calibration overhead creates bandwidth issues and
+	 * increases overall system power consumption. On the other hand,
+	 * issuing ZQ calibration long commands when exiting self-refresh is
+	 * still required.
+	 *
+	 * WORKAROUND
+	 * Because there is no power consumption benefit of the power-down due
+	 * to the calibration and there is a performance risk, the guideline
+	 * is to not allow power-down state and, therefore, to not have set
+	 * the EMIF_PWR_MGMT_CTRL[10:8] REG_LP_MODE bit field to 0x4.

- * rx_alloc_method - RX buffer allocation method
- *
- * This driver supports two methods for allocating and using RX buffers:
- * each RX buffer may be backed by an skb or by an order-n page.
- *
- * When GRO is in use then the second method has a lower overhead,
- * since we don't have to allocate then free skbs on reassembled frames.
- *
- * Values:
- *   - RX_ALLOC_METHOD_AUTO = 0
- *   - RX_ALLOC_METHOD_SKB  = 1
- *   - RX_ALLOC_METHOD_PAGE = 2
- *
- * The heuristic for %RX_ALLOC_METHOD_AUTO is a simple hysteresis count
- * controlled by the parameters below.
- *
- *   - Since pushing and popping descriptors are separated by the rx_queue
- *     size, so the watermarks should be ~rxd_size.
- *   - The performance win by using page-based allocation for GRO is less
- *     than the performance hit of using page-based allocation of non-GRO,
- *     so the watermarks should reflect this.
- *
- * Per channel we maintain a single variable, updated by each channel:
- *
- *   rx_alloc_level += (gro_performed ? RX_ALLOC_FACTOR_GRO :
- *                      RX_ALLOC_FACTOR_SKB)
- * Per NAPI poll interval, we constrain rx_alloc_level to 0..MAX (which
- * limits the hysteresis), and update the allocation strategy:
- *
- *   rx_alloc_method = (rx_alloc_level > RX_ALLOC_LEVEL_GRO ?

-	  The Configurable Composite Gadget supports multiple USB
-	  functions: acm, mass storage, rndis and FunctionFS.
-	  Each function can be configured and enabled/disabled
-	  dynamically from userspace through a sysfs interface.
-
-	  In order to compile this (either as a module or built-in),
-	  "USB Gadget Drivers" and anything under it must not be
-	  selected compiled-in in
-	  Device Drivers->USB Support->USB Gadget Support.
-	  However, you can say "M" there, if you do, the
-	  Configurable Composite Gadget can be compiled "M" only
-	  or not at all.
-
-	  BIG FAT NOTE: DON'T RELY ON THIS USERINTERFACE HERE! AS PART
-	  OF THE REWORK DONE HERE WILL BE A NEW USER INTERFACE WITHOUT ANY
-	  COMPATIBILITY TO THIS SYSFS INTERFACE HERE. BE AWARE OF THIS
-	  BEFORE SELECTING THIS.

- *	and by language IDs provided in control requests
- * @descriptors: Table of full (or low) speed descriptors, using interface and
- *	string identifiers assigned during @bind().  If this pointer is null,
- *	the function will not be available at full speed (or at low speed).
- * @hs_descriptors: Table of high speed descriptors, using interface and

- *	the function will not be available at high speed.
- * @ss_descriptors: Table of super speed descriptors, using interface and
- *	string identifiers assigned during @bind(). If this
- *	pointer is null after initiation, the function will not
- *	be available at super speed.
- * @config: assigned when @usb_add_function() is called; this is the
- *	configuration with which this function is associated.
- * @bind: Before the gadget can register, all of its functions bind() to the
- *	available resources including string and interface identifiers used
- *	in interface or class descriptors; endpoints; I/O buffers; and so on.
- * @unbind: Reverses @bind; called as a side effect of unregistering the
- *	driver which added this function.
- * @set_alt: (REQUIRED) Reconfigures altsettings; function drivers may
- *	initialize usb_ep.driver data at this time (when it is used).
- *	Note that setting an interface to its current altsetting resets
- *	interface state, and that all interfaces have a disabled state.
- * @get_alt: Returns the active altsetting.  If this is not provided,
- *	then only altsetting zero is supported.
- * @disable: (REQUIRED) Indicates the function should be disabled.  Reasons
- *	include host resetting or reconfiguring the gadget, and disconnection.
- * @setup: Used for interface-specific control requests.
- * @suspend: Notifies functions when the host stops sending USB traffic.
- * @resume: Notifies functions when the host restarts USB traffic.
- * @get_status: Returns function status as a reply to
- *	GetStatus() request when the recepient is Interface.
- * @func_suspend: callback to be called when
- *	SetFeature(FUNCTION_SUSPEND) is reseived
- *
- * A single USB function uses one or more interfaces, and should in most
- * cases support operation at both full and high speeds.  Each function is
- * associated by @usb_add_function() with a one configuration; that function
- * causes @bind() to be called so resources can be allocated as part of
- * setting up a gadget driver.  Those resources include endpoints, which
- * should be allocated using @usb_ep_autoconfig().
- *
- * To support dual speed operation, a function driver provides descriptors
- * for both high and full speed operation.  Except in rare cases that don't
- * involve bulk endpoints, each speed needs different endpoint descriptors.
- *
- * Function drivers choose their own strategies for managing instance data.
- * The simplest strategy just declares it "static', which means the function
- * can only be activated once.  If the function needs to be exposed in more
- * than one configuration at a given speed, it needs to support multiple
- * usb_function structures (one for each configuration).
- *
- * A more complex strategy might encapsulate a @usb_function structure inside
- * a driver-specific instance structure to allows multiple activations.  An
- * example of multiple activations might be a CDC ACM function that supports
- * two or more distinct instances within the same configuration, providing
- * several independent logical data links to a USB host.

- * The Mass Storage Function acts as a USB Mass Storage device,
- * appearing to the host as a disk drive or as a CD-ROM drive.  In
- * addition to providing an example of a genuinely useful composite
- * function for a USB device, it also illustrates a technique of
- * double-buffering for increased throughput.
- *
- * For more information about MSF and in particular its module
- * parameters and sysfs interface read the
- * <Documentation/usb/mass-storage.txt> file.

-
-/*
- * MSF is configured by specifying a fsg_config structure.  It has the
- * following fields:
- *
- *	nluns		Number of LUNs function have (anywhere from 1
- *				to FSG_MAX_LUNS which is 8).
- *	luns		An array of LUN configuration values.  This
- *				should be filled for each LUN that
- *				function will include (ie. for "nluns"
- *				LUNs).  Each element of the array has
- *				the following fields:
- *	->filename	The path to the backing file for the LUN.
- *				Required if LUN is not marked as
- *				removable.
- *	->ro		Flag specifying access to the LUN shall be
- *				read-only.  This is implied if CD-ROM
- *				emulation is enabled as well as when
- *				it was impossible to open "filename"
- *				in R/W mode.
- *	->removable	Flag specifying that LUN shall be indicated as
- *				being removable.
- *	->cdrom		Flag specifying that LUN shall be reported as
- *				being a CD-ROM.
- *	->nofua		Flag specifying that FUA flag in SCSI WRITE(10,12)
- *				commands for this LUN shall be ignored.
- *
- *	vendor_name
- *	product_name
- *	release		Information used as a reply to INQUIRY
- *				request.  To use default set to NULL,
- *				NULL, 0xffff respectively.  The first
- *				field should be 8 and the second 16
- *				characters or less.
- *
- *	can_stall	Set to permit function to halt bulk endpoints.
- *				Disabled on some USB devices known not
- *				to work correctly.  You should set it
- *				to true.
- *
- * If "removable" is not set for a LUN then a backing file must be
- * specified.  If it is set, then NULL filename means the LUN's medium
- * is not loaded (an empty string as "filename" in the fsg_config
- * structure causes error).  The CD-ROM emulation includes a single
- * data track and no audio tracks; hence there need be only one
- * backing file per LUN.
- *
- * This function is heavily based on "File-backed Storage Gadget" by
- * Alan Stern which in turn is heavily based on "Gadget Zero" by David
- * Brownell.  The driver's SCSI command interface was based on the
- * "Information technology - Small Computer System Interface - 2"
- * document from X3T9.2 Project 375D, Revision 10L, 7-SEP-93,
- * available at <http://www.t10.org/ftp/t10/drafts/s2/s2-r10l.pdf>.
- * The single exception is opcode 0x23 (READ FORMAT CAPACITIES), which
- * was based on the "Universal Serial Bus Mass Storage Class UFI
- * Command Specification" document, Revision 1.0, December 14, 1998,
- * available at
- * <http://www.usb.org/developers/devclass_docs/usbmass-ufi10.pdf>.

-
-/*
- *				Driver Design
- *
- * The MSF is fairly straightforward.  There is a main kernel
- * thread that handles most of the work.  Interrupt routines field
- * callbacks from the controller driver: bulk- and interrupt-request
- * completion notifications, endpoint-0 events, and disconnect events.
- * Completion events are passed to the main thread by wakeup calls.  Many
- * ep0 requests are handled at interrupt time, but SetInterface,
- * SetConfiguration, and device reset requests are forwarded to the
- * thread in the form of "exceptions" using SIGUSR1 signals (since they
- * should interrupt any ongoing file I/O operations).
- *
- * The thread's main routine implements the standard command/data/status
- * parts of a SCSI interaction.  It and its subroutines are full of tests
- * for pending signals/exceptions -- all this polling is necessary since
- * the kernel has no setjmp/longjmp equivalents.  (Maybe this is an
- * indication that the driver really wants to be running in userspace.)
- * An important point is that so long as the thread is alive it keeps an
- * open reference to the backing file.  This will prevent unmounting
- * the backing file's underlying filesystem and could cause problems
- * during system shutdown, for example.  To prevent such problems, the
- * thread catches INT, TERM, and KILL signals and converts them into
- * an EXIT exception.
- *
- * In normal operation the main thread is started during the gadget's
- * fsg_bind() callback and stopped during fsg_unbind().  But it can
- * also exit when it receives a signal, and there's no point leaving
- * the gadget running when the thread is dead.  As of this moment, MSF
- * provides no way to deregister the gadget when thread dies -- maybe
- * a callback functions is needed.
- *
- * To provide maximum throughput, the driver uses a circular pipeline of
- * buffer heads (struct fsg_buffhd).  In principle the pipeline can be
- * arbitrarily long; in practice the benefits don't justify having more
- * than 2 stages (i.e., double buffering).  But it helps to think of the
- * pipeline as being a long one.  Each buffer head contains a bulk-in and
- * a bulk-out request pointer (since the buffer can be used for both
- * output and input -- directions always are given from the host's
- * point of view) as well as a pointer to the buffer and various state
- * variables.
- *
- * Use of the pipeline follows a simple protocol.  There is a variable
- * (fsg->next_buffhd_to_fill) that points to the next buffer head to use.
- * At any time that buffer head may still be in use from an earlier
- * request, so each buffer head has a state variable indicating whether
- * it is EMPTY, FULL, or BUSY.  Typical use involves waiting for the
- * buffer head to be EMPTY, filling the buffer either by file I/O or by
- * USB I/O (during which the buffer head is BUSY), and marking the buffer
- * head FULL when the I/O is complete.  Then the buffer will be emptied
- * (again possibly by USB I/O, during which it is marked BUSY) and
- * finally marked EMPTY again (possibly by a completion routine).
- *
- * A module parameter tells the driver to avoid stalling the bulk
- * endpoints wherever the transport specification allows.  This is
- * necessary for some UDCs like the SuperH, which cannot reliably clear a
- * halt on a bulk endpoint.  However, under certain circumstances the
- * Bulk-only specification requires a stall.  In such cases the driver
- * will halt the endpoint and set a flag indicating that it should clear
- * the halt in software during the next device reset.  Hopefully this
- * will permit everything to work correctly.  Furthermore, although the
- * specification allows the bulk-out endpoint to halt when the host sends
- * too much data, implementing this would cause an unavoidable race.
- * The driver will always use the "no-stall" approach for OUT transfers.
- *
- * One subtle point concerns sending status-stage responses for ep0
- * requests.  Some of these requests, such as device reset, can involve
- * interrupting an ongoing file I/O operation, which might take an
- * arbitrarily long time.  During that delay the host might give up on
- * the original ep0 request and issue a new one.  When that happens the
- * driver should not notify the host about completion of the original
- * request, as the host will no longer be waiting for it.  So the driver
- * assigns to each ep0 request a unique tag, and it keeps track of the
- * tag value of the request associated with a long-running exception
- * (device-reset, interface-change, or configuration-change).  When the
- * exception handler is finished, the status-stage response is submitted
- * only if the current ep0 request tag is equal to the exception request
- * tag.  Thus only the most recently received ep0 request will get a
- * status-stage response.
- *
- * Warning: This driver source file is too long.  It ought to be split up
- * into a header file plus about 3 separate .c files, to handle the details
- * of the Gadget, USB Mass Storage, and SCSI protocols.

- * This function is an RNDIS Ethernet port -- a Microsoft protocol that's
- * been promoted instead of the standard CDC Ethernet.  The published RNDIS
- * spec is ambiguous, incomplete, and needlessly complex.  Variants such as
- * ActiveSync have even worse status in terms of specification.
- *
- * In short:  it's a protocol controlled by (and for) Microsoft, not for an
- * Open ecosystem or markets.  Linux supports it *only* because Microsoft
- * doesn't support the CDC Ethernet standard.
- *
- * The RNDIS data transfer model is complex, with multiple Ethernet packets
- * per USB message, and out of band data.  The control model is built around
- * what's essentially an "RNDIS RPC" protocol.  It's all wrapped in a CDC ACM
- * (modem, not Ethernet) veneer, with those ACM descriptors being entirely
- * useless (they're ignored).  RNDIS expects to be the only function in its
- * configuration, so it's no real help if you need composite devices; and
- * it expects to be the first configuration too.
- *
- * There is a single technical advantage of RNDIS over CDC Ethernet, if you
- * discount the fluff that its RPC can be made to deliver: it doesn't need
- * a NOP altsetting for the data interface.  That lets it work on some of the
- * "so smart it's stupid" hardware which takes over configuration changes
- * from the software, and adds restrictions like "no altsettings".
- *
- * Unfortunately MSFT's RNDIS drivers are buggy.  They hang or oops, and
- * have all sorts of contrary-to-specification oddities that can prevent
- * them from working sanely.  Since bugfixes (or accurate specs, letting
- * Linux work around those bugs) are unlikely to ever come from MSFT, you
- * may want to avoid using RNDIS on purely operational grounds.
- *
- * Omissions from the RNDIS 1.0 specification include:
- *
- *   - Power management ... references data that's scattered around lots
- *     of other documentation, which is incorrect/incomplete there too.
- *
- *   - There are various undocumented protocol requirements, like the need
- *     to send garbage in some control-OUT messages.
- *
- *   - MS-Windows drivers sometimes emit undocumented requests.

-/*
- * This component encapsulates the TTY layer glue needed to provide basic
- * "serial port" functionality through the USB gadget stack.  Each such
- * port is exposed through a /dev/ttyGS* node.
- *
- * After initialization (gserial_setup), these TTY port devices stay
- * available until they are removed (gserial_cleanup).  Each one may be
- * connected to a USB function (gserial_connect), or disconnected (with
- * gserial_disconnect) when the USB host issues a config change event.
- * Data can only flow when the port is connected to the host.
- *
- * A given TTY port can be made available in multiple configurations.
- * For example, each one might expose a ttyGS0 node which provides a
- * login application.  In one case that might use CDC ACM interface 0,
- * while another configuration might use interface 3 for that.  The
- * work to handle that (including descriptor management) is not part
- * of this component.
- *
- * Configurations may expose more than one TTY port.  For example, if
- * ttyGS0 provides login service, then ttyGS1 might provide dialer access
- * for a telephone or fax link.  And ttyGS2 might be something that just
- * needs a simple byte stream interface for some messaging protocol that
- * is managed in userspace ... OBEX, PTP, and MTP have been mentioned.

+Driver: adv_1724
+Description: Advantech PCI-1724U
+Author: Frank Mori Hess <fmh6jj@gmail.com>
+Status: works
+Updated: 2013-02-09
+Devices: [Advantech] PCI-1724U (adv_pci1724)
+
+Subdevice 0 is the analog output.
+Subdevice 1 is the offset calibration for the analog output.
+Subdevice 2 is the gain calibration for the analog output.
+
+The calibration offset and gains have quite a large effect
+on the analog output, so it is possible to adjust the analog output to
+have an output range significantly different from the board's
+nominal output ranges.  For a calibrated +/- 10V range, the analog
+output's offset will be set somewhere near mid-range (0x2000) and its
+gain will be near maximum (0x3fff).
+
+There is really no difference between the board's documented 0-20mA
+versus 4-20mA output ranges.  To pick one or the other is simply a matter
+of adjusting the offset and gain calibration until the board outputs in
+the desired range.
+
+Configuration options:
+   None
+
+Manual configuration of comedi devices is not supported by this driver;
+supported PCI devices are configured as comedi devices automatically.

+ * Each PPI is a 8255 chip providing 24 DIO channels.  The DIO channels
+ * are configurable as inputs or outputs in four groups:
+ *
+ *   Port A  - channels  0 to  7
+ *   Port B  - channels  8 to 15
+ *   Port CL - channels 16 to 19
+ *   Port CH - channels 20 to 23
+ *
+ * Only mode 0 of the 8255 chips is supported.
+ *
+ * Each CTR is a 8254 chip providing 3 16-bit counter channels.  Each
+ * channel is configured individually with INSN_CONFIG instructions.  The
+ * specific type of configuration instruction is specified in data[0].
+ * Some configuration instructions expect an additional parameter in
+ * data[1]; others return a value in data[1].  The following configuration
+ * instructions are supported:
+ *
+ *   INSN_CONFIG_SET_COUNTER_MODE.  Sets the counter channel's mode and
+ *     BCD/binary setting specified in data[1].
+ *
+ *   INSN_CONFIG_8254_READ_STATUS.  Reads the status register value for the
+ *     counter channel into data[1].
+ *
+ *   INSN_CONFIG_SET_CLOCK_SRC.  Sets the counter channel's clock source as
+ *     specified in data[1] (this is a hardware-specific value).  Not
+ *     supported on PC214E.  For the other boards, valid clock sources are
+ *     0 to 7 as follows:
+ *
+ *       0.  CLK n, the counter channel's dedicated CLK input from the SK1
+ *         connector.  (N.B. for other values, the counter channel's CLKn
+ *         pin on the SK1 connector is an output!)
+ *       1.  Internal 10 MHz clock.
+ *       2.  Internal 1 MHz clock.
+ *       3.  Internal 100 kHz clock.
+ *       4.  Internal 10 kHz clock.
+ *       5.  Internal 1 kHz clock.
+ *       6.  OUT n-1, the output of counter channel n-1 (see note 1 below).
+ *       7.  Ext Clock, the counter chip's dedicated Ext Clock input from
+ *         the SK1 connector.  This pin is shared by all three counter
+ *         channels on the chip.
+ *
+ *     For the PCIe boards, clock sources in the range 0 to 31 are allowed
+ *     and the following additional clock sources are defined:
+ *
+ *       8.  HIGH logic level.
+ *       9.  LOW logic level.
+ *      10.  "Pattern present" signal.
+ *      11.  Internal 20 MHz clock.
+ *
+ *   INSN_CONFIG_GET_CLOCK_SRC.  Returns the counter channel's current
+ *     clock source in data[1].  For internal clock sources, data[2] is set
+ *     to the period in ns.
+ *
+ *   INSN_CONFIG_SET_GATE_SRC.  Sets the counter channel's gate source as
+ *     specified in data[2] (this is a hardware-specific value).  Not
+ *     supported on PC214E.  For the other boards, valid gate sources are 0
+ *     to 7 as follows:
+ *
+ *       0.  VCC (internal +5V d.c.), i.e. gate permanently enabled.
+ *       1.  GND (internal 0V d.c.), i.e. gate permanently disabled.
+ *       2.  GAT n, the counter channel's dedicated GAT input from the SK1
+ *         connector.  (N.B. for other values, the counter channel's GATn
+ *         pin on the SK1 connector is an output!)
+ *       3.  /OUT n-2, the inverted output of counter channel n-2 (see note
+ *         2 below).
+ *       4.  Reserved.
+ *       5.  Reserved.
+ *       6.  Reserved.
+ *       7.  Reserved.
+ *
+ *     For the PCIe boards, gate sources in the range 0 to 31 are allowed;
+ *     the following additional clock sources and clock sources 6 and 7 are
+ *     (re)defined:
+ *
+ *       6.  /GAT n, negated version of the counter channel's dedicated
+ *         GAT input (negated version of gate source 2).
+ *       7.  OUT n-2, the non-inverted output of counter channel n-2
+ *         (negated version of gate source 3).
+ *       8.  "Pattern present" signal, HIGH while pattern present.
+ *       9.  "Pattern occurred" latched signal, latches HIGH when pattern
+ *         occurs.
+ *      10.  "Pattern gone away" latched signal, latches LOW when pattern
+ *         goes away after it occurred.
+ *      11.  Negated "pattern present" signal, LOW while pattern present
+ *         (negated version of gate source 8).
+ *      12.  Negated "pattern occurred" latched signal, latches LOW when
+ *         pattern occurs (negated version of gate source 9).
+ *      13.  Negated "pattern gone away" latched signal, latches LOW when
+ *         pattern goes away after it occurred (negated version of gate
+ *         source 10).
+ *
+ *   INSN_CONFIG_GET_GATE_SRC.  Returns the counter channel's current gate
+ *     source in data[2].
+ *
+ * Clock and gate interconnection notes:
+ *
+ *   1.  Clock source OUT n-1 is the output of the preceding channel on the
+ *   same counter subdevice if n > 0, or the output of channel 2 on the
+ *   preceding counter subdevice (see note 3) if n = 0.
+ *
+ *   2.  Gate source /OUT n-2 is the inverted output of channel 0 on the
+ *   same counter subdevice if n = 2, or the inverted output of channel n+1
+ *   on the preceding counter subdevice (see note 3) if n < 2.
+ *
+ *   3.  The counter subdevices are connected in a ring, so the highest
+ *   counter subdevice precedes the lowest.
+ *
+ * The 'TIMER' subdevice is a free-running 32-bit timer subdevice.
+ *
+ * The 'INTERRUPT' subdevice pretends to be a digital input subdevice.  The
+ * digital inputs come from the interrupt status register.  The number of
+ * channels matches the number of interrupt sources.  The PC214E does not
+ * have an interrupt status register; see notes on 'INTERRUPT SOURCES'
+ * below.

+ *
+ * When an interrupt source is enabled in the interrupt source enable
+ * register, a rising edge on the source signal latches the corresponding
+ * bit to 1 in the interrupt status register.
+ *
+ * When the interrupt status register value as a whole (actually, just the
+ * 6 least significant bits) goes from zero to non-zero, the board will
+ * generate an interrupt.  The interrupt will remain asserted until the
+ * interrupt status register is cleared to zero.  To clear a bit to zero in
+ * the interrupt status register, the corresponding interrupt source must
+ * be disabled in the interrupt source enable register (there is no
+ * separate interrupt clear register).
+ *
+ * COMMANDS
+ *
+ * The driver supports a read streaming acquisition command on the
+ * 'INTERRUPT' subdevice.  The channel list selects the interrupt sources
+ * to be enabled.  All channels will be sampled together (convert_src ==
+ * TRIG_NOW).  The scan begins a short time after the hardware interrupt
+ * occurs, subject to interrupt latencies (scan_begin_src == TRIG_EXT,
+ * scan_begin_arg == 0).  The value read from the interrupt status register
+ * is packed into a short value, one bit per requested channel, in the
+ * order they appear in the channel list.

-Driver: ni_labpc
-Description: National Instruments Lab-PC (& compatibles)
-Author: Frank Mori Hess <fmhess@users.sourceforge.net>
-Devices: [National Instruments] Lab-PC-1200 (labpc-1200),
-  Lab-PC-1200AI (labpc-1200ai), Lab-PC+ (lab-pc+), PCI-1200 (ni_labpc)
-Status: works
-
-Tested with lab-pc-1200.  For the older Lab-PC+, not all input ranges
-and analog references will work, the available ranges/arefs will
-depend on how you have configured the jumpers on your board
-(see your owner's manual).
-
-Kernel-level ISA plug-and-play support for the lab-pc-1200
-boards has not
-yet been added to the driver, mainly due to the fact that
-I don't know the device id numbers.  If you have one
-of these boards,
-please file a bug report at http://comedi.org/ 
-so I can get the necessary information from you.
-
-The 1200 series boards have onboard calibration dacs for correcting
-analog input/output offsets and gains.  The proper settings for these
-caldacs are stored on the board's eeprom.  To read the caldac values
-from the eeprom and store them into a file that can be then be used by
-comedilib, use the comedi_calibrate program.
-
-Configuration options - ISA boards:
-  [0] - I/O port base address
-  [1] - IRQ (optional, required for timed or externally triggered conversions)
-  [2] - DMA channel (optional)
-
-Configuration options - PCI boards:
-  [0] - bus (optional)
-  [1] - slot (optional)
-
-The Lab-pc+ has quirky chanlist requirements
-when scanning multiple channels.  Multiple channel scan
-sequence must start at highest channel, then decrement down to
-channel 0.  The rest of the cards can scan down like lab-pc+ or scan
-up from channel zero.  Chanlists consisting of all one channel
-are also legal, and allow you to pace conversions in bursts.

-    The PCI4520 is a PCI card.  The DM7520 is a PC/104-plus card.
-    Both have:
-    8/16 12 bit ADC with FIFO and channel gain table
-    8 bits high speed digital out (for external MUX) (or 8 in or 8 out)
-    8 bits high speed digital in with FIFO and interrupt on change (or 8 IO)
-    2 12 bit DACs with FIFOs
-    2 bits output
-    2 bits input
-    bus mastering DMA
-    timers: ADC sample, pacer, burst, about, delay, DA1, DA2
-    sample counter
-    3 user timer/counters (8254)
-    external interrupt
-
-    The DM7520 has slightly fewer features (fewer gain steps).
-
-    These boards can support external multiplexors and multi-board
-    synchronization, but this driver doesn't support that.

-    Board docs: http://www.rtdusa.com/PC104/DM/analog%20IO/dm7520.htm

-
-    Notes:
-    This board is memory mapped.  There is some IO stuff, but it isn't needed.
-
-    I use a pretty loose naming style within the driver (rtd_blah).
-    All externally visible names should be rtd520_blah.
-    I use camelCase for structures (and inside them).
-    I may also use upper CamelCase for function names (old habit).
-
-    This board is somewhat related to the RTD PCI4400 board.
-
-    I borrowed heavily from the ni_mio_common, ni_atmio16d, mite, and
-    das1800, since they have the best documented code.  Driver
-    cb_pcidas64.c uses the same DMA controller.
-
-    As far as I can tell, the About interrupt doesn't work if Sample is
-    also enabled.  It turns out that About really isn't needed, since
-    we always count down samples read.
-
-    There was some timer/counter code, but it didn't follow the right API.

-     * How to be a proc read function

-     * Prototype:
-     *    int f(char *buffer, char **start, off_t offset,
-     *          int count, int *peof, void *dat)
-     *
-     * Assume that the buffer is "count" bytes in size.
-     *
-     * If you know you have supplied all the data you
-     * have, set *peof.
-     *
-     * You have three ways to return data:
-     * 0) Leave *start = NULL.  (This is the default.)
-     *    Put the data of the requested offset at that
-     *    offset within the buffer.  Return the number (n)
-     *    of bytes there are from the beginning of the
-     *    buffer up to the last byte of data.  If the
-     *    number of supplied bytes (= n - offset) is
-     *    greater than zero and you didn't signal eof
-     *    and the reader is prepared to take more data
-     *    you will be called again with the requested
-     *    offset advanced by the number of bytes
-     *    absorbed.  This interface is useful for files
-     *    no larger than the buffer.
-     * 1) Set *start = an unsigned long value less than
-     *    the buffer address but greater than zero.
-     *    Put the data of the requested offset at the
-     *    beginning of the buffer.  Return the number of
-     *    bytes of data placed there.  If this number is
-     *    greater than zero and you didn't signal eof
-     *    and the reader is prepared to take more data
-     *    you will be called again with the requested
-     *    offset advanced by *start.  This interface is
-     *    useful when you have a large file consisting
-     *    of a series of blocks which you want to count
-     *    and return as wholes.
-     *    (Hack by Paul.Russell@rustcorp.com.au)
-     * 2) Set *start = an address within the buffer.
-     *    Put the data of the requested offset at *start.
-     *    Return the number of bytes of data placed there.
-     *    If this number is greater than zero and you
-     *    didn't signal eof and the reader is prepared to
-     *    take more data you will be called again with the
-     *    requested offset advanced by the number of bytes

+ *                       1 to 16 (default 12)
+ * @phy_type:           Specifies the type of PHY interface to use. By default,
+ *                      the driver will automatically detect the phy_type.
+ * @phy_utmi_width:     Specifies the UTMI+ Data Width (in bits). This parameter
+ *                      is applicable for a phy_type of UTMI+ or ULPI. (For a
+ *                      ULPI phy_type, this parameter indicates the data width
+ *                      between the MAC and the ULPI Wrapper.) Also, this
+ *                      parameter is applicable only if the OTG_HSPHY_WIDTH cC
+ *                      parameter was set to "8 and 16 bits", meaning that the
+ *                      core has been configured to work at either data path
+ *                      width.
+ *                       8 or 16 (default 16)
+ * @phy_ulpi_ddr:       Specifies whether the ULPI operates at double or single
+ *                      data rate. This parameter is only applicable if phy_type
+ *                      is ULPI.

+ *                           data bus (default)
+ *                       1 - double data rate ULPI interface with 4 bit wide
+ *                           data bus
+ * @phy_ulpi_ext_vbus:  For a ULPI phy, specifies whether to use the internal or
+ *                      external supply to drive the VBus
+ * @i2c_enable:         Specifies whether to use the I2Cinterface for a full
+ *                      speed PHY. This parameter is only applicable if phy_type
+ *                      is FS.
+ *                       0 - No (default)
+ *                       1 - Yes
+ * @ulpi_fs_ls:         True to make ULPI phy operate in FS/LS mode only
+ * @ts_dline:           True to enable Term Select Dline pulsing
+ * @en_multiple_tx_fifo: Specifies whether dedicated per-endpoint transmit FIFOs
+ *                      are enabled
+ * @reload_ctl:         True to allow dynamic reloading of HFIR register during
+ *                      runtime
+ * @ahb_single:         This bit enables SINGLE transfers for remainder data in
+ *                      a transfer for DMA mode of operation.
+ *                       0 - remainder data will be sent using INCR burst size
+ *                       1 - remainder data will be sent using SINGLE burst size
+ * @otg_ver:            OTG version supported

+ *                      interval counter that determines when it needs to be
+ *                      scheduled for execution. This scheduling mechanism
+ *                      allows only a simple calculation for periodic bandwidth

+ *                      need to execute in the same frame). However, it greatly
+ *                      simplifies scheduling and should be sufficient for the
+ *                      vast majority of OTG hosts, which need to connect to a
+ *                      small number of peripherals at one time. Items move from
+ *                      this list to periodic_sched_ready when the QH interval
+ *                      counter is 0 at SOF.
+ * @periodic_sched_ready:  List of periodic QHs that are ready for execution in
+ *                      the next frame, but have not yet been assigned to host
+ *                      channels. Items move from this list to
+ *                      periodic_sched_assigned as host channels become
+ *                      available during the current frame.
+ * @periodic_sched_assigned: List of periodic QHs to be executed in the next
+ *                      frame that are assigned to host channels. Items move
+ *                      from this list to periodic_sched_queued as the
+ *                      transactions for the QH are queued to the DWC_otg
+ *                      controller.
+ * @periodic_sched_queued: List of periodic QHs that have been queued for
+ *                      execution. Items move from this list to either
+ *                      periodic_sched_inactive or periodic_sched_ready when the
+ *                      channel associated with the transfer is released. If the
+ *                      interval for the QH is 1, the item moves to
+ *                      periodic_sched_ready because it must be rescheduled for
+ *                      the next frame. Otherwise, the item moves to
+ *                      periodic_sched_inactive.
+ * @periodic_usecs:     Total bandwidth claimed so far for periodic transfers.
+ *                      This value is in microseconds per (micro)frame. The
+ *                      assumption is that all periodic transfers may occur in
+ *                      the same (micro)frame.
+ * @frame_number:       Frame number read from the core at SOF. The value ranges
+ *                      from 0 to HFNUM_MAX_FRNUM.
+ * @periodic_qh_count:  Count of periodic QHs, if using several eps. Used for
+ *                      SOF enable/disable.
+ * @free_hc_list:       Free host channels in the controller. This is a list of
+ *                      struct dwc2_host_chan items.
+ * @periodic_channels:  Number of host channels assigned to periodic transfers.
+ *                      Currently assuming that there is a dedicated host
+ *                      channel for each periodic transaction and at least one
+ *                      host channel is available for non-periodic transactions.
+ * @non_periodic_channels: Number of host channels assigned to non-periodic
+ *                      transfers
+ * @hc_ptr_array:       Array of pointers to the host channel descriptors.
+ *                      Allows accessing a host channel descriptor given the
+ *                      host channel number. This is useful in interrupt
+ *                      handlers.
+ * @status_buf:         Buffer used for data received during the status phase of
+ *                      a control transfer.
+ * @status_buf_dma:     DMA address for status_buf

 - get DRM Maintainer review for this code
+- Wait for common display framework to hit mainline and update the IPU

 - Factor out more code to common helper functions
 - decide where to put the base driver. It is not specific to a subsystem

 Todo:
-	- checkpatch.pl cleanups
-	- sparse cleanups
-	- lots of little modules, should be merged together
-	  and added to the build.
-	- testing?
-	- handle churn in v4l layer.
+	- create an API for motion detection
+	- let s2250-board use i2c subdevs as well instead of hardcoding
+	  support for the i2c devices.
+	- when the driver is moved out of staging, support for saa7134-go7007
+	  should be added to the saa7134 driver. The patch for that is

  * Video queues is initialized by uvc_queue_init(). The function performs
  * basic initialization of the uvc_video_queue struct and never fails.
  *
- * Video buffer allocation and freeing are performed by uvc_alloc_buffers and
- * uvc_free_buffers respectively. The former acquires the video queue lock,
- * while the later must be called with the lock held (so that allocation can
- * free previously allocated buffers). Trying to free buffers that are mapped
- * to user space will return -EBUSY.
- *
- * Video buffers are managed using two queues. However, unlike most USB video
- * drivers that use an in queue and an out queue, we use a main queue to hold
- * all queued buffers (both 'empty' and 'done' buffers), and an irq queue to
- * hold empty buffers. This design (copied from video-buf) minimizes locking
- * in interrupt, as only one queue is shared between interrupt and user
- * contexts.
- *
- * Use cases
- * ---------
- *
- * Unless stated otherwise, all operations that modify the irq buffers queue
- * are protected by the irq spinlock.
- *
- * 1. The user queues the buffers, starts streaming and dequeues a buffer.
- *
- *    The buffers are added to the main and irq queues. Both operations are
- *    protected by the queue lock, and the later is protected by the irq
- *    spinlock as well.
- *
- *    The completion handler fetches a buffer from the irq queue and fills it
- *    with video data. If no buffer is available (irq queue empty), the handler
- *    returns immediately.
- *
- *    When the buffer is full, the completion handler removes it from the irq
- *    queue, marks it as ready (UVC_BUF_STATE_DONE) and wakes its wait queue.
- *    At that point, any process waiting on the buffer will be woken up. If a
- *    process tries to dequeue a buffer after it has been marked ready, the
- *    dequeing will succeed immediately.
- *
- * 2. Buffers are queued, user is waiting on a buffer and the device gets
- *    disconnected.
- *
- *    When the device is disconnected, the kernel calls the completion handler
- *    with an appropriate status code. The handler marks all buffers in the
- *    irq queue as being erroneous (UVC_BUF_STATE_ERROR) and wakes them up so
- *    that any process waiting on a buffer gets woken up.
- *
- *    Waking up up the first buffer on the irq list is not enough, as the
- *    process waiting on the buffer might restart the dequeue operation
- *    immediately.
- *
+ * Video buffers are managed by videobuf2. The driver uses a mutex to protect
+ * the videobuf2 queue operations by serializing calls to videobuf2 and a
+ * spinlock to protect the IRQ queue that holds the buffers to be processed by
+ * the driver.

-/* MUSB PERIPHERAL status 3-mar-2006:
- *
- * - EP0 seems solid.  It passes both USBCV and usbtest control cases.
- *   Minor glitches:
- *
- *     + remote wakeup to Linux hosts work, but saw USBCV failures;
- *       in one test run (operator error?)
- *     + endpoint halt tests -- in both usbtest and usbcv -- seem
- *       to break when dma is enabled ... is something wrongly
- *       clearing SENDSTALL?
- *
- * - Mass storage behaved ok when last tested.  Network traffic patterns
- *   (with lots of short transfers etc) need retesting; they turn up the
- *   worst cases of the DMA, since short packets are typical but are not
- *   required.
- *
- * - TX/IN
- *     + both pio and dma behave in with network and g_zero tests
- *     + no cppi throughput issues other than no-hw-queueing
- *     + failed with FLAT_REG (DaVinci)
- *     + seems to behave with double buffering, PIO -and- CPPI
- *     + with gadgetfs + AIO, requests got lost?
- *
- * - RX/OUT
- *     + both pio and dma behave in with network and g_zero tests
- *     + dma is slow in typical case (short_not_ok is clear)
- *     + double buffering ok with PIO
- *     + double buffering *FAILS* with CPPI, wrong data bytes sometimes
- *     + request lossage observed with gadgetfs
- *
- * - ISO not tested ... might work, but only weakly isochronous
- *
- * - Gadget driver disabling of softconnect during bind() is ignored; so
- *   drivers can't hold off host requests until userspace is ready.
- *   (Workaround:  they can turn it off later.)
- *
- * - PORTABILITY (assumes PIO works):
- *     + DaVinci, basically works with cppi dma
- *     + OMAP 2430, ditto with mentor dma
- *     + TUSB 6010, platform-specific dma in the works

+ * integer.
+ *
+ * This could result in an unaligned 32-bit read.  For example, if the cursor

+ * the top line of the cursor.  We do a 32-bit read of 'image', but we look
