uses of __constant_cpu_to_{endian} as well.

From db1dd4d376134eba0e08af523b61cc566a4ea1cd Mon Sep 17 00:00:00 2001

Subject: Use f_lock to protect f_flags

Traditionally, changes to struct file->f_flags have been done under BKL
protection, or with no protection at all.  This patch causes all f_flags
changes after file open/creation time to be done under protection of
f_lock.  This allows the removal of some BKL usage and fixes a number of

Subject: USB: add quirk to avoid config and interface strings

Apparently the Configuration and Interface strings aren't used as
often as the Vendor, Product, and Serial strings.  In at least one
device (a Saitek Cyborg Gold 3D joystick), attempts to read the
Configuration string cause the device to stop responding to Control
requests.

This patch (as1226) adds a quirks flag, telling the kernel not to
read a device's Configuration or Interface strings, together with a
new quirk for the offending joystick.

Subject: USB: gadget: fix rndis regression

Restore some code that was wrongly dropped from the RNDIS
driver, and caused interop problems observed with OpenMoko.

The issue is with hardware which needs help conforming to part
of the USB 2.0 spec (section 8.5.3.2); some can automagically
send a ZLP in response to an unexpected IN, but not all chips
will do that.  We don't need to check the packet length ourselves
the way earlier code did, since the UDC must already check it.
But we do need to tell the UDC when it must force a short packet
termination of the data stage.

(Based on a patch from Aric D. Blumer <aric at sdgsystems.com>)

Subject: USB: usb-storage: increase max_sectors for tape drives

This patch (as1203) increases the max_sector limit for USB tape
drives.  By default usb-storage sets max_sectors to 240 (i.e., 120 KB)
for all devices.  But tape drives need a higher limit, since tapes can
and do have very large block sizes.  Without the ability to transfer
an entire large block in a single command, such tapes can't be used.

This fixes Bugzilla #12207.

Subject: usblp: continuously poll for status
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The usblp in 2.6.18 polled for status regardless if we actually needed it.
At some point I dropped it, to save the batteries if nothing else.
As it turned out, printers exist (e.g. Canon BJC-3000) that need prodding
this way or else they stop. This patch restores the old behaviour.
If you want to save battery, don't leave jobs in the print queue.

I tested this on my printers by printing and examining usbmon traces
to make sure status is being requested and printers continue to print.
Tuomas Jäntti verified the fix on BJC-3000.

Subject: USB: gpio_vbus: add delayed vbus_session calls

Call usb_gadget_vbus_connect() and ...disconnect() from a
workqueue rather than from an irq handler, allowing msleep()
calls in vbus_session.  Update kerneldoc to match.

Subject: USB: pxa27x_udc: add vbus session handling

On vbus_session() call, optionally activate D+ pullup
resistor and enable the udc, or deactivate D+ pullup
resistor and disable the udc.

It is intentional to not handle any VBus sense related irq.
An external transceiver driver (like gpio_vbus) should
catch VBus sense signal, and call usb_gadget_vbus_connect()
or usb_gadget_vbus_disconnect().

Subject: USB: pxa27x_udc: add otg transceiver support

When a transceiver driver is used, no automatic udc enable
is done. The transceiver (OTG or not) should :
 - take care of VBus sensing
 - call usb_gadget_vbus_connect()
 - call usb_gadget_vbus_disconnect()

The pullup should remain within this driver's management,
either by gpio_pullup of udc_command() fields.

Subject: USB: pxa27x_udc: add vbus_draw callback

Add the vbus_draw() callback to inform the transceiver, if
it exists, how much current may be drawn. The decision is
taken on gadget driver side using the configuration chosen
by the host and its bMaxPower field.  Some systems can use
the host's VBUS supply to augment or recharge a battery.
(There's also a default of 100 mA for unconfigured devices,
or 8 mA if they're OTG devices.)

Subject: USB: drivers: use USB API functions rather than constants

This set of patches introduces calls to the following set of functions:

usb_endpoint_dir_in(epd)
usb_endpoint_dir_out(epd)
usb_endpoint_is_bulk_in(epd)
usb_endpoint_is_bulk_out(epd)
usb_endpoint_is_int_in(epd)
usb_endpoint_is_int_out(epd)
usb_endpoint_num(epd)
usb_endpoint_type(epd)
usb_endpoint_xfer_bulk(epd)
usb_endpoint_xfer_control(epd)
usb_endpoint_xfer_int(epd)
usb_endpoint_xfer_isoc(epd)

In some cases, introducing one of these functions is not possible, and it
just replaces an explicit integer value by one of the following constants:

USB_ENDPOINT_XFER_BULK
USB_ENDPOINT_XFER_CONTROL
USB_ENDPOINT_XFER_INT
USB_ENDPOINT_XFER_ISOC

An extract of the semantic patch that makes these changes is as follows:

From 664d5df92e88b6ef091048a802b3750f4e989180 Mon Sep 17 00:00:00 2001
From: Werner Cornelius <werner@cornelius-consult.de>
Date: Fri, 16 Jan 2009 21:02:41 +0100
Subject: USB: usb-serial ch341: support for DTR/RTS/CTS

Fixup of Werner Cornelius patch to the ch341 USB-serial driver, which adds:
- support all baudrates, not just a hard-coded set
- support for controlling DTR, RTS and CTS

Features still missing:
- character length other than 8 bits
- parity settings
- break control

I adapted his patch for the new usb_serial API introduced in 2.6.25-git8 by
Alan Cox on 22 July 2008. Non-compliance to the new API was a reason for
refusing a similar patch from Tollef Fog Heen.

Usage example by Tollef Fog Heen :
        TEMPer USB thermometer <http://err.no/src/TEMPer.c>

Subject: USB: suspend/resume support for option driver

This patch implements suspend and resume methods for the
option driver. With my hardware I can even suspend the system
and keep up a connection for a short time.

Subject: USB: serial: introduce a flag into the usb serial layer to tell
 drivers that their URBs are killed due to suspension

This patch introduces a flag into the usb serial layer to tell drivers
that their URBs are killed due to suspension. That is necessary to let
drivers know whether they should report an error back.

Signed-off-by: Oliver Neukum <oneukum@suse.de>

Hi Greg,

this is for 2.6.30. Patches to use this in drivers are under development.

	Regards
		Oliver

Subject: USB: serial generic resume function fix

This removes an unnecessary check for autoresume from the generic
resume method. The check has been obsoleted by the now delayed
increase of the usage counter which makes the error this check prevented
impossible. This change allows drivers which only use the bulk read URB
the use of the generic method even if they support autosuspend.

 serial layer

This patch makes use of the generic method if a serial driver provides
no implementation. This simplifies implementing suspend/resume support
in serial drivers.

Subject: USB: ftdi_sio: remove pointless syslog spew

Remove some pointless messages from the FTDI serial driver;
I found these filling up syslog on one system.  Also remove
a pointless "break" after a "return" in the same area.

Subject: USB: otg: adding nop usb transceiver

NOP transceiver is used by all the usb transceiver which are mostly
autonomous and doesn't require any programming or which are built
into the usb ip itself.NOP transceiver only allocates the memory
for struct xceiv and calls otg_set_transceiver() so function call
to otg_get_transceiver() will return a valid transceiver.

NOP transceiver device should be registered by calling
usb_nop_xceiv_register() from platform files.

Subject: USB: serial: remove recourse to generic method

This removes the fallback to the generic method. It is cleaner to
explicitely request it. Introducing this was my mistake. This will
be solved by an explicit test and the driver being allowed to request
what it needs to be done upon resumption.

Subject: USB: serial: refuse to open recently removed USB Serial devices

A USB-serial converter device is plugged into a system, and a process
opens it's device node.  If the device is physically removed whilst the
process still has its device node open, then other processes can
sucessfully open the now non-existent device's node.  I would expect
that open() on a device that has been physically removed should return
ENODEV.

This is manifesting itself with getty on my system.  I do the following:
1.  set up inittab to spawn getty on ttyUSB0, eg:
    T1:23:respawn:/sbin/getty -L ttyUSB0 115200 vt100
2.  Plug in USB-serial converter cable
3.  Wait for a login prompt on a terminal program attached to the serial
    cable
4.  Login
5.  Pull the USB-serial converter cable from the box
6.  getty doesn't realise that ttyUSB0 no longer exists as /dev/ttyUSB0
    can still be opened.
7.  Re-insert the USB-serial converter cable
8.  You should no longer get a login prompt over the serial cable, as
    the the USB-serial cable now shows up as /dev/ttyUSB1, and getty is
    trying to talk to /dev/ttyUSB0.

The attached patch will cause open("/dev/ttyUSB0", O_RDONLY) to return
ENODEV after the USB-serial converter has been pulled.  The patch was
created against 2.6.28.1.  I can supply it against something else if
needs be.  It is fairly simple, so should be OK.

I am using a pl2303 device, although I don't think that makes any
difference.

Subject: USB: fix USB_STORAGE_CYPRESS_ATACB

commit 64a87b24: [SCSI] Let scsi_cmnd->cmnd use request->cmd buffer
changed the scsi_eh_prep_cmnd logic by making it clear
the ->cmnd buffer. But the sat to cypress atacb translation supposed
the ->cmnd buffer wasn't modified.

This patch makes it set the ->cmnd buffer after scsi_eh_prep_cmnd call.
The problem and a fix was reported by Matthieu CASTET <castet.matthieu@free.fr>

It also removes all the hackery fiddling of scsi_cmnd and scsi_eh_save by
requesting from scsi_eh_prep_cmnd to prepare a read into ->sense_buffer,
which is much more suitable a buffer for HW transfers, then after the command
execution the regs read is copied into regs buffer before actual preparation
of sense_buffer.

Also fix an alien comment character to my utf-8 editor.

Subject: USB: EHCI: add software retry for transaction errors

This patch (as1204) adds a software retry mechanism to ehci-hcd.  It
gets invoked when the driver encounters transaction errors on an
asynchronous endpoint.  On many systems, hardware deficiencies cause
such errors to occur if one device is unplugged while the host is
communicating with another device.  With the patch, the failed
transactions are retried and generally succeed the second or third
time through.

This is based on code originally written by Koichiro Saito.

Subject: USB: Make the isp1760_register function prototype more generic

The patch changes the prototype of the isp1760_register() function to use
predefined types like phys_addr_t and resource_size_t rather than u64

Subject: USB: Add platform device support for the ISP1760 USB chip

Currently, the driver only supports PCI and PPC_OF but there are
boards like ARM RealView where this is a platform device. The patch adds
the necessary functions and registration to the isp1760-if.c file and
modifies the corresponding Makefile and Kconfig to be able to use this
driver even if PCI and PPC_OF are not enabled.

Subject: USB: symbolserial: log the ioctl commands

We need to figure out what userspace programs are expecting from this
driver, so log them so we can try to get it right.

Subject: USB: serial: add qualcomm wireless modem driver

Driver originally written by Qualcomm, but rewritten by me due to the
totally different coding style.  Cleaned up the probe logic to make a
bit more sense, this is one wierd device.  They could have prevented all
of this by just writing sane firmware for the modem.

Subject: usb-serial: fix usb_serial_register bug when boot with nousb param

With "nousb" cmdline booting, built-in serial drivers (ie. airecable)
will trigger kernel oops.

Indeed, if nousb, usb_serial_init will failed, and the usb serial bus type
will not be registerd, then usb_serial_register call driver_register
which try to register the driver to a not registered bus.

Here add usb_disabled() check in usb_serial_register to fix it.

Subject: usb-storage: prepare for subdriver separation

This patch (as1206) is the first step in converting usb-storage's
subdrivers into separate modules.  It makes the following large-scale
changes:

	Remove a bunch of unnecessary #ifdef's from usb_usual.h.
	Not truly necessary, but it does clean things up.

	Move the USB device-ID table (which is duplicated between
	libusual and usb-storage) into its own source file,
	usual-tables.c, and arrange for this to be linked with
	either libusual or usb-storage according to whether
	USB_LIBUSUAL is configured.

	Add to usual-tables.c a new usb_usual_ignore_device()
	function to detect whether a particular device needs to be
	managed by a subdriver and not by the standard handlers
	in usb-storage.

	Export a whole bunch of functions in usb-storage, renaming
	some of them because their names don't already begin with
	"usb_stor_".  These functions will be needed by the new
	subdriver modules.

	Split usb-storage's probe routine into two functions.
	The subdrivers will call the probe1 routine, then fill in
	their transport and protocol settings, and then call the
	probe2 routine.

	Take the default cases and error checking out of
	get_transport() and get_protocol(), which run during
	probe1, and instead put a check for invalid transport
	or protocol values into the probe2 function.

	Add a new probe routine to be used for standard devices,
	i.e., those that don't need a subdriver.  This new routine
	checks whether the device should be ignored (because it
	should be handled by ub or by a subdriver), and if not,
	calls the probe1 and probe2 functions.

Subject: usb-storage: make sddr09 a separate module

This patch (as1207) converts usb-storage's sddr09 subdriver into a
separate module.

An unexpected complication arises because of DPCM devices, in which
one LUN uses the sddr09 transport and one uses the standard CB
transport.  Since these devices can be used even when
USB_STORAGE_SDDR09 isn't configured, their entries in unusual_devs.h
require special treatment.  If SDDR09 isn't configured then the
entries remain in unusual_devs.h; if it is then the entries are
present in unusual_sddr09.h instead.

Subject: USB: usb-storage: added missing MODULE_LICENSE("GPL") for usb-storage
 ums-* modules

The lack of a MODULE_LICENSE macro in ums-* subdrivers prevented them
from loading. Needs to be applied after Alan Stern's usb-storage
subdriver separation patchset. Also added missing MODULE_DESCRIPTION and
MODULE_AUTHOR entries.

Subject: USB: allow libusb to talk to unauthenticated WUSB devices

To permit a userspace application to associate with WUSB devices
using numeric association, control transfers to unauthenticated WUSB
devices must be allowed.

This requires that wusbcore correctly sets the device state to
UNAUTHENTICATED, DEFAULT and ADDRESS and that control transfers can be
performed to UNAUTHENTICATED devices.

Subject: USB: musb: rewrite host periodic endpoint allocation

The current MUSB host code doesn't make use of all the available
FIFOs in for periodic transfers since it wrongly assumes the RX
and TX sides of any given hw_ep always share one FIFO.

Change:  use 'in_qh' and 'out_qh' fields of the 'struct musb_hw_ep'
to check the endpoint's business; get rid of the now-unused 'periodic'
array in the 'struct musb'.  Also optimize a loop induction variable
in the endpoint lookup code.

(Based on a previous patch from Ajay Kumar Gupta <ajay.gupta@ti.com>)

Subject: USB: musb: NAK timeout scheme on bulk RX endpoint

Fixes endpoint starvation issue when more than one bulk QH is
multiplexed on the reserved bulk RX endpoint, which is normal
for cases like serial and ethernet adapters.

This patch sets the NAK timeout interval for such QHs, and when
a timeout triggers the next QH will be scheduled.  (This resembles
the bulk scheduling done in hardware by EHCI, OHCI, and UHCI.)

This scheme doesn't work for devices which are connected to a
high to full speed tree (transaction translator) as there is
no NAK timeout interrupt from the musb controller from such
devices.

Tested with PIO, Inventra DMA, CPPI DMA.

  clarify only for bulk RX; don't accidentally clear WZC bits ]

Correct musb_read_fifosize() and musb_configure_ep0() functions
for the #ifndef BLACKFIN branch when the silicon uses static FIFO
configuration.  (Most current silicon configures this controller
to use dynamic FIFO configuration; some parts from ST don't, like
the STM STA2062.)

Subject: USB: musb: only turn off vbus in OTG hosts

Except on DaVinci, VBUS is now switched off as part of idling the
USB link (after a_wait_bcon) whenever a device is disconnected
from host.  This is correct for OTG hosts, where either SRP or
an ID interrupt could turn VBUS on again.

However, for non-OTG hosts there's no way to turn VBUS on again,
so the host becomes unusable.  And the procfs entry which once
allowed a manual workaround for this is now gone.

This patch adds an is_otg_enabled() check before scheduling the
switch-off timer in disconnect path, supporting a "classic host"
mode where SRP is unavailable.

Partial support for DaVinci DM355, on the EVM board; peripheral
mode should work, once mainline merges DM355 support.  Missing:

  (a) renumbering the GPIO for DRVVBUS on the DM6446 EVM,
      when DAVINCI_N_GPIO increases;

  (b) disabling DM355_DEEPSLEEP.DRVVBUS_OVERRIDE so VBUS is
      driven according to the ID signal, if cpu_is_..._dm355()

The new PHY control bits are ignored on DM6446.

Subject: USB: ch341 serial: fix port number changed after resume

This patch fixes the following bug:
	.plug ch341 usb serial port into a hub port;
	.ch341 driver bound to the device and /dev/ttyUSB0 comes
	.open /dev/ttyUSB0 by minicom and we can use the serial successfully
	.suspend the ch341 usb serial device(such as: echo suspend > power/level)
	.resume the ch341 usb serial device (such as: echo on > power/level)
	.new port /dev/ttyUSB1 comes ,and the original /dev/ttyUSB0 still exists,
but is no longer usable by minicom

The patch adds suspend and resume callback to ch341 usb driver to prevent it
from unbinding during suspend. The /dev/ttyUSB0 is not released until being
closed, so /dev/ttyUSB1 comes after resume, and the original /dev/ttyUSB0 is
no longer usable by minicom. It is really a mess for a minicom user.

This patch also adds the reset_resume callback to make it usable after resuming
from STR or hibernation, for generally STR or hibernation will make the vbus
of root-hub lost.

Finally enable the driver's supports_autosuspend, for the device is in working
order with it.

Subject: USB: usbmon: Add binary API v1

This patch adds an extension to the binary API so it reaches parity with
existing text API (so-called "1u"). The extension delivers additional data,
such as ISO descriptors and the interrupt interval.

Subject: USB: uhci: don't use pseudo negative values

The code in uhci-q.c doesn't have to use pseudo-negative values.  I did
it that way because it was easy and because it would give the expected
output during debugging.  But it doesn't have to work that way.  Here's
another approach.

Subject: USB: make transfer_buffer_lengths in struct urb field u32

Roel Kluin pointed out that transfer_buffer_lengths in struct urb was
declared as an 'int'.  This patch changes this field to be 'u32' to
prevent any potential negative conversion and comparison errors.

This triggered a few compiler warning messages when these fields were
being used with the min macro, so they have also been fixed up in this
patch.

Subject: USB: don't send Set-Interface after reset

This patch (as1221) changes the way usbcore reinitializes a device
following a reset or a reset-resume.  Currently we call
usb_set_interface() for every interface in the active configuration;
this is to put the interface into the same altsetting as before the
reset and to make sure that the host's endpoint state matches the
device's endpoint state.

However, sending a Set-Interface request is a waste of time if an
interface was already in altsetting 0 before the reset, since it is
certainly in altsetting 0 afterward.  In addition, many devices can't
handle Set-Interface requests -- they crash when they receive them.

So instead, the patch adds code to check each interface.  If the
interface wasn't in altsetting 0 before the reset, we go head with the
Set-Interface request as before.  But if it was then we skip sending
the Set-Interface request, and we clear out the host-side endpoint
state by calling usb_disable_interface() followed by
usb_enable_interface().

The patch also adds a couple of new comments to explain what's going
on.

function cp2101_quantise_baudrate rounds the baud rate as per AN205
Table 1.  A modification to the baud rate calculation removes a rounding
error, allowing the full range of baud rates to be used.

Subject: USB: serial: rename cp2101 driver to cp210x

Lots of users are getting confused about the cp2101 driver.  It really
does support more than just the cp2101 device, so rename it to cp210x to
try to prevent confusion.

Subject: USB: ipaq: handle 4 endpoint devices

The ipaq driver currently enforces one port on all devices. This
is correct for 2 and 3 endpoint devices, but with 4 endpoint devices
meaningful communication occurs on the second pair.

This patch allows 2 ports for 4 endpoint devices.

Subject: USB: Fix cp2101 USB serial device driver termios functions for
 console use

This is really a follow up to the modifications Alan Cox made for commit
95da310e66ee8090119596c70ca8432e57f9a97f to pass a tty_struct to various
interface functions, which broke the serial configuration (termios) functions
when the device is being used as a console. These changes restore the
configuration to proper functioning both as a tty and as a console.  As Alan
notes in that commit, these changes will need to be tweaked when we have
a proper console abstraction.

Subject: USB: more u32 conversion after transfer_buffer_length and
 actual_length

transfer_buffer_length and actual_length have become unsigned, therefore some
additional conversion of local variables, function arguments and print
specifications is desired.

A test for a negative urb->transfer_buffer_length became obsolete; instead
we ensure that it does not exceed INT_MAX. Also, urb->actual_length is always
less than urb->transfer_buffer_length.

rh_string() does no longer return -EPIPE in the case of an unsupported ID.
Instead its only caller, rh_call_control() does the check.

Subject: USB: gadget: composite device-level suspend/resume hooks

Address one open question in the composite gadget framework:
Yes, we should have device-level suspend/resume callbacks
in addition to the function-level ones.  We have at least one
scenario (with gadget zero in OTG test mode) that's awkward
to handle without it.

Subject: USB: gadget: gadget zero uses new suspend/resume hooks

Use the new device-level suspend/resume hooks for Gadget Zero;
always enable them with the OTG test mode; and support remote
wakeup on both configurations even in non-OTG mode.

This ensures that both configurations can pass the USBCV remote
wakeup tests when the OTG test mode is enabled.  This changes
behavior by adding autoresume support to the loopback config
even in non-OTG mode; the test failure was that it didn't work
in OTG mode.

Subject: USB: allow malformed LANGID descriptors

When an USB hardware does not provide a valid LANGID, fall back to value
zero which is still a reasonable default for most devices.

Subject: USB: isp1760: Add a delay before reading the SKIPMAP registers in
 isp1760-hcd.c

The data read from the SKIPMAP registers is not immediately available
after writing and the driver panics when a packet is enqueued from the
interrupt handler. This patch adds an ndelay(195) before these registers
are read (delay value mentioned in section 15.1.1.3 of the ISP1760 data
sheet).
