The readsl and writesl I/O accessors are only defined on some
architectures. The driver currently depends on CONFIG_ARM because
the build breaks on x86, in particular. Switch to use of ioread32_rep
and iowrite32_rep to fix build on all architectures and remove the
CONFIG_ARM dependency.
Also update printk formatting to handle a long long dma_addr_t to avoid
warnings on !32-bit architectures.

Commit 3dc6475 ("bcm63xx_enet: add support Broadcom BCM6345 Ethernet")
changed the ENETDMA[CS] macros such that they are no longer macros, but
actual register offset definitions. The bcm63xx_udc driver was not
updated, and as a result, causes the following build error to pop up:
CC drivers/usb/gadget/u_ether.o
drivers/usb/gadget/bcm63xx_udc.c: In function 'iudma_write':
drivers/usb/gadget/bcm63xx_udc.c:642:24: error: called object '0' is not
a function
drivers/usb/gadget/bcm63xx_udc.c: In function 'iudma_reset_channel':
drivers/usb/gadget/bcm63xx_udc.c:698:46: error: called object '0' is not
a function
drivers/usb/gadget/bcm63xx_udc.c:700:49: error: called object '0' is not
a function
Fix this by updating usb_dmac_{read,write}l and usb_dmas_{read,write}l to
take an extra channel argument, and use the channel width
(ENETDMA_CHAN_WIDTH) to offset the register we want to access, hence
doing again what the macro implicitely did for us.

musb_port_reset() is called from musb_hub_control() which in turn holds
a spinlock, so musb_port_reset() is not allowed to call msleep().
With the asynchronous work helpers in place, this is fortunately easy to
fix by rescheduling the reset deassertion function to after the time
when the wait period is finished.
Note, however, that the MUSB_POWER_RESUME bit is only set on AM33xx
processors under rare conditions such as when to another driver
reporting an error during suspend. Hence, this didn't hit me yet in
normal operation.

During resume don't touch SUSPENDM/RESUME bits of POWER register
while restoring controller context. These bits might be changed
by the controller during resume operation and so will be different
than what they were during suspend.
e.g. SUSPENDM bit is set by software during USB global suspend but
automatically cleared by the controller during remote wakeup or
during resume. Setting this bit back while restoring context
causes undesired behaviour. i.e. Babble interrupt is generated
and USB is broken.

Disables PING on status phase of control transfer.
PING token is not mandatory in status phase of control transfer
and so some high speed USB devices don't support it. If such devices
are connected to MUSB then they would not respond to PING token
causing delayed or failed enumeration.

phy_power_off() can, depending on the PHY being used,
start I2C transactions which shouldn't happen in
atomic context.
Current call to phy_power_off() inside omap2430_runtime
callbacks causes the following dump, as a fix, just don't
power off the PHY in runtime.

The ohci-platform driver checks for misconfigurations in cases where
the Device Tree data specifies big-endian registers or descriptors but
the corresponding driver config settings have not been enabled. As
Jonas Gorski suggested, we may as well apply the same check to general
platform data too.
This requires moving the code that sets the big-endian quirk flags
from the ohci_platform_reset() routine into ohci_platform_probe(), and
moving the checks out of the DT-specific "if" statement clause.
The patch also changes the text of the error messages in an attempt to

The initial versions of the devicetree enablement patches for ehci-platform
used "ehci-platform" as compatible string. However this was disliked by various
reviewers because the platform bus is a Linux invention and devicetree is
supposed to be OS agnostic. After much discussion I gave up, added a:
"depends on !PPC_OF" to Kconfig to avoid a known conflict with PPC-OF platforms
and went with the generic usb-ehci as requested.
In retro-spect I should have chosen something different, the dts files for many
existing boards already claim to be compatible with "usb-ehci", ie they have:
compatible = "ti,ehci-omap", "usb-ehci";
In theory this should not be a problem since the "ti,ehci-omap" entry takes
presedence, but in practice using a conflicting compatible string is an issue,
because it makes which driver gets used depend on driver registration order.
This patch changes the compatible string claimed by ehci-platform to
"generic-ehci", avoiding the driver registration / module loading ordering
problems, and removes the "depends on !PPC_OF" workaround.

According to the spec for the DWC2 controller, when the PRTINT interrupt fires,
the application must clear the appropriate status bit in the Host Port Control
and Status register to clear this bit.
When disconnecting an A-cable when the dwc2 host driver, the PRTINT fires, but
only the GINTSTS_PRTINT status is cleared, no action is done with the HPRT0
register. The HPRT0_ENACHG bit in the HPRT0 must also be poked to correctly
clear the GINTSTS_PRTINT interrupt.
I am seeing this behavoir on v2.93 of the DWC2 IP. When I disconnect an OTG
A-cable adapter, the PRTINT interrupt fires when the DWC2 is in device mode
and is never cleared.
This patch adds the function to read the HPRT0 register when the PRTINT fires
and the dwc2 IP has already transitioned to device mode. This function is only
clearing the HPRT0_ENACHG bit for now, but can be modified to handle more.

commit 804fad45411b48233b48003e33a78f290d227c8 "USBNET: ax88179_178a:
enable tso if usb host supports sg dma", it broke the device under xHCI
1.0 hosts. Under certain network loads, the device would see an
unexpected short packet from the host, which would cause the device to
stop sending ethernet packets, even through USB packets would still be
sent.
Commit 35773dac5f86 "usb: xhci: Link TRB must not occur within a USB
payload burst" attempted to fix this. It was a quick hack to partially
implement the TD fragment rules. However, it caused regressions in the
usb-storage layer and userspace USB drivers using libusb. The patches
to attempt to fix this are too far reaching into the USB core, and we
really need to implement the TD fragment rules correctly in the xHCI
driver, instead of continuing to wallpaper over the issues.
Disable arbitrarily-aligned scatter-gather in the xHCI driver for 1.0
hosts. Only the ax88179_178a driver checks the no_sg_constraint flag,
so don't set it for 1.0 hosts. This should not impact usb-storage or
usbfs behavior, since they pass down max packet sized aligned sg-list
entries (512 for USB 2.0 and 1024 for USB 3.0).

Currently ehci-platform is only used in combination with devicetree when used
with some Via socs. By extending it to (optionally) get clks and a phy from
devicetree, and enabling / disabling those on power_on / off, it can be used
more generically. Specifically after this commit it can be used for the
ehci controller on Allwinner sunxi SoCs.
Since ehci-platform is intended to handle any generic enough non pci ehci
device, add a "usb-ehci" compatibility string.
There already is a usb-ehci device-tree bindings document, update this
with clks and phy bindings info.
Although actually quite generic so far the via,vt8500 compatibilty string
had its own bindings document. Somehow we even ended up with 2 of them. Since
these provide no extra information over the generic usb-ehci documentation,
this patch removes them.
The ehci-ppc-of.c driver also claims the usb-ehci compatibility string,
even though it mostly is ibm,usb-ehci-440epx specific. ehci-platform.c is
not needed on ppc platforms, so add a !PPC_OF dependency to it to avoid
2 drivers claiming the same compatibility string getting build on ppc.

This modifies the probing order so that any matching
dynamic entry always will be used, even if the driver
has a matching static entry.
It is sometimes useful to dynamically update existing
device entries. With the new ability to set the dynamic
entry driver_info field, this can be used to test new
additions to class driver exception lists or proposed
changes to existing static per-device driver_info
entries.

This driver was previously an interface driver. Since USB/IP
exports a whole device, not just an interface, it would make
sense to be a device driver.
This patch also modifies the way userspace sees and uses a
shared device:
* the usbip_status file is no longer created for interface 0, but for
the whole device (such as
/sys/devices/pci0000:00/0000:00:01.2/usb1/1-1/usbip_status).
* per interface information, such as interface class or protocol, is
no longer sent/received; only device specific information is
transmitted.
* since the driver was moved one level below in the USB architecture,
there is no need to bind/unbind each interface, just the device as a
whole.

People sometimes create their own custom-configured kernels and forget
to enable CONFIG_SCSI_MULTI_LUN. This causes problems when they plug
in a USB storage device (such as a card reader) with more than one
LUN.
Fortunately, we can tell fairly easily when a storage device claims to
have more than one LUN. When that happens, this patch asks the SCSI
layer to probe all the LUNs automatically, regardless of the config
setting.
The patch also updates the Kconfig help text for usb-storage,
explaining that CONFIG_SCSI_MULTI_LUN may be necessary.

The Cypress ATACB unusual-devs entry for the Super Top SATA bridge
causes problems. Although it was originally reported only for
bcdDevice = 0x160, its range was much larger. This resulted in a bug
report for bcdDevice 0x220, so the range was capped at 0x219. Now
Milan reports errors with bcdDevice 0x150.
Therefore this patch restricts the range to just 0x160.

the PHY layer is supposed to be optional,
considering some PHY have no control bus
for SW to poke around.
After commit 1ae5799 (usb: hcd: Initialize
USB phy if needed) any HCD which didn't provide
a PHY driver would emit annoying error messages.
In this patch we're decreasing those messages
to debugging only and we also add a PHY prefix
or use dev_dbg so we know where they're coming from.

The move from the staging tree to the main tree exposed a
longstanding memory corruption bug in the dwc2 driver. The
reordering of the driver initialization caused the dwc2 driver
to corrupt the initialization data of the sdhci driver on the
Raspberry Pi platform, which made the bug show up.
The error is in calling to_usb_device(hsotg->dev), since ->dev
is not a member of struct usb_device. The easiest fix is to
just remove the offending code, since it is not really needed.
Thanks to Stephen Warren for tracking down the cause of this.

xhci: Fix some regressions introduced in 3.14.
Hi Greg,
Here's four patches for 3.14.
One of them adds an xHCI host quirk, and the other three of them fix
regressions introduced in 3.14. One regression causes USB 3.0 Link PM to
be enabled on all xHCI hosts (even those that may not support it), which
causes some USB 3.0 devices to not enumerate. A second regression causes
some xHCI hosts that don't support 64-bit addressing to stop responding to
commands and die.
Note, these patches don't fix the recent usbfs regression that was caused
by commit 35773dac5f862cb1c82ea151eba3e2f6de51ec3e "usb: xhci: Link TRB
must not occur within a USB payload burst". I'm waiting for those patches
to be tested.
Please pull usb-linus into usb-next, as I have feature patches that rely on
140e3026a57a Revert "usbcore: set lpm_capable field for LPM capable root
hubs"
