The immediately preceding gpio_direction_output() already set the value,
so there's no need to repeat it. This also prevents gpio_set_value() from
WARNing when the GPIO is sleepable (e.g. is on an I2C expander); the set
direction API is always sleepable, but plain set_value isn't.

This patch (as1547) rearranges the Power Management parts of the
ehci-tegra driver to match the conventions used in other EHCI platform
drivers. In particular, the controller should not be powered down by
the root hub's suspend routine; the controller's power level should be
managed by the controller's own PM methods.
The end result of the patch is that the standard ehci_bus_suspend()
and ehci_bus_resume() methods can be used instead of special-purpose
routines. The driver now uses the standard dev_pm_ops methods instead
of legacy power management. Since there is no supported wakeup
mechanism for the controller, runtime suspend is forbidden by default
(this can be overridden via sysfs, if desired).
These adjustments are needed in order to make ehci-tegra compatible
with recent changes to the USB core. The core now checks the root
hub's status following bus suspend; if the controller is automatically
powered down during bus suspend then the check will fail and the root
hub will be resumed immediately. Doing the controller power-down in a
separate method avoids this problem.

This new driver registers the NXP ISP1301 chip via the I2C subsystem. The chip
is the USB transceiver shared by ohci-nxp, lpc32xx_udc (gadget) and
isp1301_omap.
ISP1301 is a very low-level driver that primarily separates out the I2C client
registration of the ISP1301 chip (including instantiation via DT), used by
other drivers, and declares the chip's registers. It's only a helper driver for
some OHCI and USB device drivers. The driver can be considered as a register
set extension of ohci-nxp, lpc32xx-udc and isp1301_omap, which in turn know
best what to do with the low level functionality (individual ISP1301 registers
and timing, see the different initialization strategies in those drivers).
Those drivers previously internally duplicated ISP1301 register definitions
which is solved by this new isp1301 driver. The ISP1301 registers exposed via
isp1301.h can be accessed by other drivers using it with standard i2c_smbus_*()
accesses.
Following patches let the respective USB host and gadget drivers use this
driver, instead of duplicating ISP1301 handling.

A few more fixes for v3.4-rc cycle.
It includes a couple of fixes to the ordering of the methods in udc-core.c.
Without these two patches, we will have issues when either unregistering a
gadget driver (triggered with dummy_hcd only) or issuing a device-initiated
disconnect through sysfs.
There's also a fix on dummy_hcd to not call ->pullup() from udc_stop() because
udc-core.c already handles that.
A fix to MUSB as promised, to kill the compile warnings regarding deprecated
interfaces. We are essentially dropping the __deprecated flag because it
doesn't look like we will ever be able to live without it when we consider the
amount of silicon issues we find on different MUSB instantiations.
A couple of other fixes are also available, one adding the missing transceiver
events to gpio_vbus and another adding a missing unregister call to MUSB's
davinci glue layer.

This patch (as1548) fixes a recently-introduced incompatibility
between the UDC core and the dummy-hcd driver. Commit
8ae8090c82 (usb: gadget: udc-core: fix
asymmetric calls in remove_driver) moved the usb_gadget_udc_stop()
call in usb_gadget_remove_driver() below the usb_gadget_disconnect()
call.
As a result, usb_gadget_disconnect() gets called at a time when the
gadget driver believes it has been unbound but dummy-hcd believes
it has not. A nasty error ensues when dummy-hcd calls the gadget
driver's disconnect method a second time.
To fix the problem, this patch moves the gadget driver's unbind
notification after the usb_gadget_disconnect() call. Now nothing
happens between the two unbind notifications, so nothing goes wrong.

In the SetPortFeature/USB_PORT_FEAT_ENABLE case, ehci_hub_control()
would read from status_reg, modify the value, and write the result back to
status_reg. This would clear any bits in PORT_RWC_BITS that were set in
the register. Fix this by masking these bits off before the write.
This is logically the same change as 6d5f89c "USB: EHCI: remove
PORT_RWC_BITS when clearing USB_PORT_FEAT_ENABLE", but applied to the
Tegra driver rather than the USB core.

ULPI PHYs have a reset signal, and different boards use a different GPIO
for this task. Add a property to device tree to represent this.
I'm not sure if adding this property to the EHCI controller node is
entirely correct; perhaps eventually we should have explicit separate
nodes for the various PHYs. However, we don't have that right now, so this
binding seems like a reasonable choice.

The interface data should not be used as a flag to signal disconnect.
Now that all serial drivers use the usb_serial disconnect flag and

there's no need to clear it at disconnect.

This patch (as1545) fixes a problem affecting several ASUS computers:
The machine crashes or corrupts memory when going into suspend if the
ehci-hcd driver is bound to any controllers. Users have been forced
to unbind or unload ehci-hcd before putting their systems to sleep.
After extensive testing, it was determined that the machines don't
like going into suspend when any EHCI controllers are in the PCI D3
power state. Presumably this is a firmware bug, but there's nothing
we can do about it except to avoid putting the controllers in D3
during system sleep.
The patch adds a new flag to indicate whether the problem is present,
and avoids changing the controller's power state if the flag is set.
Runtime suspend is unaffected; this matters only for system suspend.
However as a side effect, the controller will not respond to remote
wakeup requests while the system is asleep. Hence USB wakeup is not
functional -- but of course, this is already true in the current state
of affairs.
This fixes Bugzilla #42728.

The ehci-hcd driver is a little haphazard about keeping track of the
state of the USBCMD register. The ehci->command field is supposed to
hold the register's value (apart from a few special bits) at all
times, but it isn't maintained properly.
This patch (as1543) cleans up the situation. It keeps ehci->command
up-to-date, and uses that value rather than reading the register from
the hardware whenever possible.

drivers/usb/musb/musb_io.h provides default implementations for
{read,write}s[bwl]() on most platforms, some of which will conflict soon
with platform-specific counterparts on m68k.
To avoid having to add more platform-specific checks to musb_io.h later,
make sure {read,write}s[bwl]() are always defined on m68k, and disable the
default implementations in musb_io.h on m68k, like is already done for
several other architectures.

In the ClearPortFeature/USB_PORT_FEAT_ENABLE case, ehci_hub_control()
would read from status_reg, clear PORT_PE, and write the result back to
status_reg. This would clear any bits in PORT_RWC_BITS that were set in

Since this masking is common across all ClearPortFeature cases, move it

This patch (as1541) corrects a small mistake in ehci-hcd. The IAAD
(Interrupt on Async Advance Doorbell) bit in the USBCMD register is
designed, as its name says, to act as a "doorbell". That is, the
driver activates the bit by setting it to 1, and the hardware
deactivates it later by setting it back to 0. The driver cannot clear
the bit by writing a 0 to it; such writes are simply ignored.
Therefore there is no reason for ehci-hcd to try to clear the bit.
The patch removes the two instances where such attempts occur.

This patch (as1542) changes the criterion ehci-hcd uses to tell when
it needs to resume the controller's root hub. A resume is needed when
a port status change is detected, obviously, but only if the root hub
is currently suspended.
Right now the driver tests whether the root hub is running, and that
is not the correct test. In particular, if the controller has died
then the root hub should not be restarted. In addition, some buggy
hardware occasionally requires the root hub to be running and
sending out SOF packets even while it is nominally supposed to be

In the end, the test needs to be changed. Rather than checking whether
the root hub is currently running, the driver will now check whether
the root hub is currently suspended. This will yield the correct
behavior in all cases.

This patch (as154) fixes a self-deadlock that occurs when userspace
writes to the bConfigurationValue sysfs attribute for a hub with
children. The task tries to lock the bandwidth_mutex at a time when
it already owns the lock:
The attribute's method calls usb_set_configuration(),
which calls usb_disable_device() with the bandwidth_mutex
held.
usb_disable_device() unregisters the existing interfaces,
which causes the hub driver to be unbound.
The hub_disconnect() routine calls hub_quiesce(), which
calls usb_disconnect() for each of the hub's children.
usb_disconnect() attempts to acquire the bandwidth_mutex
around a call to usb_disable_device().
The solution is to make usb_disable_device() acquire the mutex for
itself instead of requiring the caller to hold it. Then the mutex can
cover only the bandwidth deallocation operation and not the region
where the interfaces are unregistered.
This has the potential to change system behavior slightly when a
config change races with another config or altsetting change. Some of
the bandwidth released from the old config might get claimed by the
other config or altsetting, make it impossible to restore the old
config in case of a failure. But since we don't try to recover from
config-change failures anyway, this doesn't matter.
[This should be marked for stable kernels that contain the commit
fccf4e8620 "USB: Free bandwidth when
usb_disable_device is called."
That commit was marked for stable kernels as old as 2.6.32.]

If the PHYs are reset at during usbhs core driver, host ports will

For musb we have a fix for a kernel oops when unloading
omap2430.ko glue layer, proper error checking for pm_runtime_*,
fix for the ULPI transfer block, and a bug fix in musb_cleanup_urb

For s3c-hsotg we have mostly FIFO-related fixes (proper TX FIFO

big transfers with DMA).
For the dwc3 driver we have a memory leak fix, a very important

ep0 requests bigger than wMaxPacketSize.
On top of that there's a bunch of gadget driver minor fixes adding

All patches have been pending on the mailing list for quite a while

The OMAP1 OHCI driver needs to enable the OCPI IP block before it can
work. Previously, the driver was simply calling a symbol defined in
the OMAP platform code, but this is incorrect: drivers should be fully
decoupled from platform and architecture code.
So instead, modify the driver to call through a platform_data function
pointer instead. We skip any DT aspect, since OMAP1 is not scheduled
to be converted to DT in the near future.
This resolves the following sparse warning:
It also gets rid of a cpu_is_omap16xx() call in a driver.
In the long term, it probably makes sense to move the OCPI bus code to
somewhere under drivers/. This should avoid the whole platform_data/DT
issue with this function.

The caller is allowed to specify the GFP flags for these functions.
We should prefer their flags unless we have good reason. For

When the Seagate Goflex USB3.0 device is attached to VIA xHCI
host, sometimes the device will downgrade mode to high speed.
By the USB analyzer, I found the device finished the link
training process and worked at superspeed mode. But the device
descriptor got from the device shows the device works at 2.1.
It is very strange and seems like the device controller of
Seagate Goflex has a little confusion.
The first 8 bytes of device descriptor should be:
12 01 00 03 00 00 00 09
But the first 8 bytes of wrong device descriptor are:
12 01 10 02 00 00 00 40
The wrong device descriptor caused the initialization of mass
storage failed. After a while, the device would be recognized
as a high speed device and works fine.
This patch will warm reset the device to fix the issue after
finding the bcdUSB field of device descriptor isn't 0x0300
but the speed mode of device is superspeed.
This patch should be backported to kernels as old as 3.2, or ones that
contain the commit 75d7cf72ab "usbcore:

The xHCI 1.0 spec errata released on June 13, 2011, changes the ordering
that the xHCI registers are saved and restored in. It moves the
interrupt pending (IMAN) and interrupt control (IMOD) registers to be
saved and restored last. I believe that's because the host controller
may attempt to fetch the event ring table when interrupts are
re-enabled. Therefore we need to restore the event ring registers
before we re-enable interrupts.

When xhci_mem_cleanup() is called, we can't be sure if the xHC is
actually halted. We can ask the xHC to halt by writing to the RUN bit
in the command register, but that might timeout due to a HW hang.
If the host controller is still running, we should not write zeroed
values to the event ring dequeue pointers or base tables, the DCBAA
pointers, or the command ring pointers. Eric Fu reports his VIA VL800
host accesses the event ring pointers after a failed register restore on
resume from suspend. The hypothesis is that the host never actually
halted before the register write to change the event ring pointer to
zero.
Remove all writes of zeroed values to pointer registers in
xhci_mem_cleanup(). Instead, make all callers of the function reset the
host controller first, which will reset those registers to zero.
xhci_mem_init() is the only caller that doesn't first halt and reset the
host controller before calling xhci_mem_cleanup().
This should be backported to kernels as old as 2.6.32.

Eric Fu reports a problem with his VIA host controller fetching a zeroed
event ring pointer on resume from suspend. The host should have been
halted, but we can't be sure because that code ignores the return value
from xhci_halt(). Print a warning when the host controller refuses to
halt within XHCI_MAX_HALT_USEC (currently 16 seconds).
(Update: it turns out that the VIA host controller is reporting a halted
state when it fetches the zeroed event ring pointer. However, we still
need this warning for other host controllers.)

- For Control Read transfer, the ACK handshake on an IN transaction
may be corrupted, so the device may not receive the ACK for data
stage, the complete irq will not occur at this situation.
Therefore, we need to move prime status stage from complete irq
routine to the place where the data stage has just primed, or the
host will never get ACK for status stage.
The above issue has been described at USB2.0 spec chapter 8.5.3.3.
- After adding prime status stage just after prime the data stage,
there is a potential problem when the status dTD is added before the data stage
has primed by hardware. The reason is the device's dTD descriptor has NO direction bit,
if data stage (IN) prime hasn't finished, the status stage(OUT)
dTD will be added at data stage dTD's Next dTD Pointer, so when the data stage
transfer has finished, the status dTD will be primed as IN by hardware,
then the host will never receive ACK from the device side for status stage.
- Delete below code at fsl_ep_queue:
/* Update ep0 state */
if ((ep_index(ep) == 0))
udc->ep0_state = DATA_STATE_XMIT;
the udc->ep0_state will be updated again after udc->driver->setup
finishes.

When runtime_pm was originally added, it was done in rather confusing
way: omap2430_musb_init() (called from musb_init_controller) would do
runtime_pm_get_sync() and musb_init_controller() itself would do
runtime_pm_put to balance it out. This is not only confusing but also
wrong if non-omap2430 glue layer is used.
This confusion resulted in commit 772aed45b6 "usb: musb: fix
pm_runtime mismatch", that removed runtime_pm_put() from
musb_init_controller as that looked unbalanced, and also happened to
fix unrelated isp1704_charger crash. However this broke runtime PM
functionality (musb is now always powered, even without gadget active).
Avoid these confusing runtime pm dependences by making
musb_init_controller() and omap2430_musb_init() do their own runtime
get/put pairs; also cover error paths. Remove unneeded runtime_pm_put
in omap2430_remove too. isp1704_charger crash that motivated
772aed45b6 will be fixed by following patch.

This change prevents runtime suspend and resume actual execution, if
omap2430 controller driver is loaded after musb-hdrc, and therefore the
controller isn't initialized properly.
The problem is reproducible with 3.1.y and 3.2 kernels.

This patch (as1533) fixes a race between root-hub suspend and remote
wakeup. If a wakeup event occurs while a root hub is suspending, it
might not cause the suspend to fail. Although the host controller
drivers check for pending wakeup events at the start of their
bus_suspend routines, they generally do not check for wakeup events
while the routines are running.
In addition, if a wakeup event occurs any time after khubd is frozen
and before the root hub is fully suspended, it might not cause a
system sleep transition to fail. For example, the host controller
drivers do not fail root-hub suspends when a connect-change event is
pending.
To fix both these issues, this patch causes hcd_bus_suspend() to query
the controller driver's hub_status_data method after a root hub is
suspended, if the root hub is enabled for wakeup. Any pending status
changes will count as wakeup events, causing the root hub to be
resumed and the overall suspend to fail with -EBUSY.
A significant point is that not all events are reflected immediately
in the status bits. Both EHCI and UHCI controllers notify the CPU
when remote wakeup begins on a port, but the port's suspend-change
status bit doesn't get set until after the port has completed the
transition out of the suspend state, some 25 milliseconds later.
Consequently, the patch will interpret any nonzero return value from
hub_status_data as indicating a pending event, even if none of the
status bits are set in the data buffer. Follow-up patches make the
necessary changes to ehci-hcd and uhci-hcd.

There are two issues here, one is that the device is generating
spurious very fast modem status line changes somewhere:
CTS becomes high then low 18µs later:
[121226.924373] ftdi_process_packet: prev rng=0 dsr=10 dcd=0 cts=6
[121226.924378] ftdi_process_packet: status=10 prev=00 diff=10
[121226.924382] ftdi_process_packet: now rng=0 dsr=10 dcd=0 cts=7
(wake_up_interruptible is called)
[121226.924391] ftdi_process_packet: prev rng=0 dsr=10 dcd=0 cts=7
[121226.924394] ftdi_process_packet: status=00 prev=10 diff=10
[121226.924397] ftdi_process_packet: now rng=0 dsr=10 dcd=0 cts=8
(wake_up_interruptible is called)
This wakes up the task in TIOCMIWAIT:
[121226.924405] ftdi_ioctl: 19451 rng=0->0 dsr=10->10 dcd=0->0 cts=6->8
(wait from 20:51:46 returns and observes both changes)
Which then calls TIOCMIWAIT again:
20:51:46.400239 ioctl(3, TIOCMIWAIT, 0x20) = 0
22:11:09.441818 ioctl(3, TIOCMGET, [TIOCM_DTR|TIOCM_RTS]) = 0
22:11:09.442812 ioctl(3, TIOCMIWAIT, 0x20) = -1 EIO (Input/output error)
(the second wake_up_interruptible takes effect and an I/O error occurs)
The other issue is that TIOCMIWAIT will wait forever (unless the task is
interrupted) if the device is removed.
This change removes the -EIO return that occurs if the counts don't
appear to have changed. Multiple counts may have been processed as
one or the waiting task may have started waiting after recording the
current count.
It adds a bool to indicate that the device has been removed so that
TIOCMIWAIT doesn't wait forever, and wakes up any tasks so that they can
return -EIO.

Handling of TIOCMIWAIT was changed by commit 1d749f9afa
USB: ftdi_sio.c: Use ftdi async_icount structure for TIOCMIWAIT, as in other drivers
FTDI_STATUS_B0_MASK does not indicate the changed modem status lines,
it indicates the value of the current modem status lines. An xor is
still required to determine which lines have changed.
The count was only being incremented if the line was high. The only
reason TIOCMIWAIT still worked was because the status packet is
repeated every 1ms, so the count was always changing. The wakeup
itself still ran based on the status lines changing.
This change fixes handling of updates to the modem status lines and
allows multiple processes to use TIOCMIWAIT concurrently.
Tested with two processes waiting on different status lines being
toggled independently.

This patch (as1532) fixes a mistake in the USB suspend code. When the
system is going to sleep, we should ignore errors in powering down USB
devices, because they don't really matter. The devices will go to low
power anyway when the entire USB bus gets suspended (except for
SuperSpeed devices; maybe they will need special treatment later).
However we should not ignore errors in suspending root hubs,
especially if the error indicates that the suspend raced with a wakeup
request. Doing so might leave the bus powered on while the system was
supposed to be asleep, or it might cause the suspend of the root hub's
parent controller device to fail, or it might cause a wakeup request
to be ignored.
The patch fixes the problem by ignoring errors only when the device in
question is not a root hub.

This patch (as1536) fixes a bug in the USB serial core. Unloading and
reloading a serial driver while a serial device is plugged in causes
errors because of the code in usb_serial_disconnect() that tries to
make sure the port_remove method is called. With the new order of
driver registration introduced in the 3.4 kernel, this is definitely
not the right thing to do (if indeed it ever was).
The patch removes that whole section code, along with the mechanism
for keeping track of each port's registration state, which is no
longer needed. The driver core can handle all that stuff for us.
Note: This has been tested only with one or two USB serial drivers.
In theory, other drivers might still run into trouble. But if they
do, it will be the fault of the drivers, not of this patch -- that is,
the drivers will need to be fixed.

This patch (as1517b) fixes an error in the USB scatter-gather library.
The library code uses urb->dev to determine whether or nor an URB is
currently active; the completion handler sets urb->dev to NULL.
However the core unlinking routines need to use urb->dev. Since
unlinking always racing with completion, the completion handler must
not clear urb->dev -- it can lead to invalid memory accesses when a
transfer has to be cancelled.
This patch fixes the problem by getting rid of the lines that clear
urb->dev after urb has been submitted. As a result we may end up
trying to unlink an URB that failed in submission or that has already
completed, so an extra check is added after each unlink to avoid
printing an error message when this happens. The checks are updated
in both sg_complete() and sg_cancel(), and the second is updated to
match the first (currently it prints out unnecessary warning messages
if a device is unplugged while a transfer is in progress).

* A handful of build error and warning fixes for various platforms
* cpufreq kconfig dependencies, build and lowlevel debug fixes for

technically regressions for 3.4, but they're valid fixes and we're still
relatively early in the rc cycle so it seems appropriate to include them.

Change number of ports to 3 for newer SoCs. Modify pdata structure
and ohci-at91 code that was dealing with ports information and check
of port indexes.
Several coding style errors have been addresses as the patch was touching
affected lines of code and was producing errors while run through
checkpatch.pl.

The DT information are filled in a pdata structure and then passed on
to the usual check code of the probe function. Thus we do not need to
redo the gpio checking and irq configuration in the DT-related code.
On the other hand, we setup GPIO direction in driver for vbus and
overcurrent. It will be useful when moving to pinctrl subsystem.

Merge tag 'split-asm_system_h-for-linus-20120328' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system
Pull "Disintegrate and delete asm/system.h" from David Howells:
"Here are a bunch of patches to disintegrate asm/system.h into a set of
separate bits to relieve the problem of circular inclusion
dependencies.
I've built all the working defconfigs from all the arches that I can
and made sure that they don't break.
The reason for these patches is that I recently encountered a circular
dependency problem that came about when I produced some patches to
optimise get_order() by rewriting it to use ilog2().
This uses bitops - and on the SH arch asm/bitops.h drags in
asm-generic/get_order.h by a circuituous route involving asm/system.h.
The main difficulty seems to be asm/system.h. It holds a number of
low level bits with no/few dependencies that are commonly used (eg.
memory barriers) and a number of bits with more dependencies that
aren't used in many places (eg. switch_to()).
These patches break asm/system.h up into the following core pieces:
(1) asm/barrier.h
Move memory barriers here. This already done for MIPS and Alpha.
(2) asm/switch_to.h
Move switch_to() and related stuff here.
(3) asm/exec.h
Move arch_align_stack() here. Other process execution related bits
could perhaps go here from asm/processor.h.
(4) asm/cmpxchg.h
Move xchg() and cmpxchg() here as they're full word atomic ops and
frequently used by atomic_xchg() and atomic_cmpxchg().
(5) asm/bug.h
Move die() and related bits.
(6) asm/auxvec.h
Move AT_VECTOR_SIZE_ARCH here.
Other arch headers are created as needed on a per-arch basis."
Fixed up some conflicts from other header file cleanups and moving code
around that has happened in the meantime, so David's testing is somewhat
weakened by that. We'll find out anything that got broken and fix it..

Pull ARM platform updates from Russell King:
"This covers platform stuff for platforms I have a direct interest in
(iow, I have the hardware). Essentially:
- as we no longer support any other Acorn platforms other than RiscPC
anymore, we can collect all that code into mach-rpc.
- convert Acorn expansion card stuff to use IRQ allocation functions,
and get rid of NO_IRQ from there.
- cleanups to the ebsa110 platform to move some private stuff out of
its header files.
- large amount of SA11x0 updates:
- conversion of private DMA implementation to DMA engine support
(this actually gives us greater flexibility in drivers over the old
API.)
- re-worked ucb1x00 updates - convert to genirq, remove sa11x0
dependencies, fix various minor issues
- move platform specific sa11x0 framebuffer data into platform files
in arch/arm instead of keeping this in the driver itself
- update sa11x0 IrDA driver for DMA engine, and allow it to use DMA
for SIR transmissions as well as FIR
- rework sa1111 support for genirq, and irq allocation
- fix sa1111 IRQ support so it works again
- use sparse IRQ support
After this, I have one more pull request remaining from my current
set, which I think is going to be the most problematical as it
generates 8 conflicts."

Pull PCI changes (including maintainer change) from Jesse Barnes:
"This pull has some good cleanups from Bjorn and Yinghai, as well as
some more code from Yinghai to better handle resource re-allocation
when enabled.
There's also a new initcall_debug feature from Arjan which will print
out quirk timing information to help identify slow quirks for fixing
or refinement (Yinghai sent in a few patches to do just that once the
new debug code landed).
Beyond that, I'm handing off PCI maintainership to Bjorn Helgaas.
He's been a core PCI and Linux contributor for some time now, and has
kindly volunteered to take over. I just don't feel I have the time
for PCI review and work that it deserves lately (I've taken on some
other projects), and haven't been as responsive lately as I'd like, so
I approached Bjorn asking if he'd like to manage things. He's going
to give it a try, and I'm confident he'll do at least as well as I
have in keeping the tree managed, patches flowing, and keeping things
stable."

| USB: gadget: __init and __exit tags removed
|
| __init, __initdata and __exit tags have have been removed from
| various files to make it possible for gadgets that do not use
| the __init/__exit tags to use those.
obviously missed (at least) this case leading to a section mismatch in

This driver can be used as a subdriver of another USB driver, allowing
it to export a Device Managment interface consisting of a single interrupt
endpoint with no dedicated USB interface.
Some devices provide a Device Management function combined with a wwan
function in a single USB interface having three endpoints (bulk in/out
+ interrupt). If the interrupt endpoint is used exclusively for DM
notifications, then this driver can support that as a subdriver
provided that the wwan driver calls the appropriate entry points on
probe, suspend, resume, pre_reset, post_reset and disconnect.
The main driver must have full control over all interface related
settings, including the needs_remote_wakeup flag. A manage_power
function must be provided by the main driver.
A manage_power stub doing direct flag manipulation is used in normal
driver mode.

The kernel doc entry for usb_unlink_urb() contains the phrase "This
request is always asynchronous.". The "always" leads to the assumption
that the ->complete() callback is not called from within
usb_unlink_urb(). This is not true. The HCD is allowed to call the
->complete() from within ->urb_dequeue() if it is appropriate for the
hardware.
This patch updates the kernel doc so usb-device driver authors make sure
to drop all locks (and make sure it is okay to drop them) which are
acquired by the complete callback before calling usb_unlink_urb().

This patch updates the cp210x driver to support CP210x multiple
interface devices devices from Silicon Labs. The existing driver
always sends control requests to interface 0, which is hardcoded in
the usb_control_msg function calls. This only allows for single
interface devices to be used, and causes a bug when using ports on an
interface other than 0 in the multiple interface devices.
Here are the changes included in this patch:
- Updated the device list to contain the Silicon Labs factory default
VID/PID for multiple interface CP210x devices
- Created a cp210x_port_private struct created for each port on
startup, this struct holds the interface number
- Added a cp210x_release function to clean up the cp210x_port_private
memory created on startup
- Modified usb_get_config and usb_set_config to get a pointer to the
cp210x_port_private struct, and use the interface number there in the
usb_control_message wIndex param

To quote Dirk:
This commit introduces a check for the USB PHY clock.
Problem is that CTRL_PHY_CLK_VALID bit seems not to be present
on all Freescale ehci implementations, at least P1022 does not

The highlight on this merge is the support for Samsung's Exynos platform,

Note that Samsung Exynos glue layer will only compile on platforms which
provide implementation for the clk API for now. Once Samsung supports
pm_runtime, that limitation can be dropped from the Makefile.

If we have a non-ISOC endpoint, we will not have a Link TRB
pointing to the beginning of the TRB pool. On such endpoints,
we don't want to let the driver wrap around the TRB pool
otherwise controller will hang waiting for a valid TRB.

There's really no point in having hcd->irq as a
signed integer when we consider the fact that
IRQ 0 means NO_IRQ. In order to avoid confusion,
make hcd->irq unsigned and fix users who were

For am5536udc we have just simple coding style fixes. Nothing that has any
potential to cause any issues going forward.
With mv_udc, there's only one single change removing an unneeded NULL check.
at91_udc also only saw a single change this merge window, and that's only
removing a duplicated header.
The Renesas controller has a few more involved changes. Support for SUDMAC was
added, there's now a special handling of IRQ resources for when the IRQ line is
shared between Renesas controller and SUDMAC, we also had a bug fix where
Renesas controller would sleep in atomic context while doing DMA transfers from
a tasklet. There were also a set of minor cleanups.
The FSL UDC also had a scheduling in atomic context bug fix, but that's all.
Thanks to Sebastian, the dummy_hcd now works better than ever with support for
scatterlists and streams. Sebastian also added SuperSpeed descriptors to the
serial gadgets.
The highlight on this merge is the addition of a generic API for mapping and
unmapping usb_requests. This will avoid code duplication on all UDC controllers
and also kills all the defines for DMA_ADDR_INVALID which UDC controllers
sprinkled around. A few of the UDC controllers were already converted to use
this new API.

USB: transceiver changes for 3.4
Here we have a big rework done by Heikki Krogerus (thanks) which
splits OTG functionality away from transceivers.
We have known for quite a long time that struct otg_transceiver was
a bad name for the structure, considering transceiver is far from
being OTG-specific (see 4e67185).
a patch making modules behave better, there's a fix on debugfs'
error path, a small change removing an unnecessary pm_runtime
call on musb_shutdown() and a fix to relesect the endpoint in
Interrupt context.
This last patch is needed because we must drop musb's lock when
calling request->complete() and that could cause problems if another
thread queues a request and ends up changing MUSB_INDEX register.

This is the first cut at a driver for the Fintek F81232 USB to serial
single port converter. This provides the initial framework for the
device, and some data can move through it, but no line settings are
handled, so it's not that useful yet. It does give people a starting
place to work from.
Thank to Fintek for providing samples and specifications, without which,
this driver would have never been able to be written.
