USB: mass_storage: eject LUNs on thread exit
Adds a fallback which forces all LUNs ejection (including
non-removable and with prevent_medium_removal flag) when mass storage
function (MSF) worker thread exits and gadget fails to handle the
situation.
Previously, if thread_exits was not specified mass storage function
(MSF) did nothing when exiting thread as it's unclear for *function*
what to do when it's thread terminates so responsibility of handling
this situation was left to the *gadget* using the function.
The g_mass_storage handled the situation by unregistering itself (the
same thing that file storage gadget does). However, g_multi did
nothing and so MSF did not eject LUNs which prevented file system
unmounting.

USB: pxa27x_udc: Fix deadlocks on request queueing
As reported by Antonio, there are cases where the ep->lock
can be taken twice, triggering a deadlock.
The typical sequence is :
irq_handler
\
-> gadget.complete()
\
-> pxa27x_udc.pxa_ep_queue() : ep->lock is taken
\
-> gadget.complete()
\
-> pxa27x_udc.pxa_ep_queue() : ep->lock is taken
==> *deadlock*
The patch fixes this by :
- releasing the lock each time gadget.complete() is called
- adding a check in handle_ep() to detect a recursive call,
in which case the function becomes on no-op.
The patch is still not good enough for ep0. For this unique
endpoint, another well thought over patch will be needed.

USB: serial: add support for serial port on the moschip 7715
Add support for the serial port on devices based on the MosChip 7715,
which provides a serial and parallel port on a single usb interface.
This is added to the existing driver for the Moschip 7720 dual serial
port device. The 7715 is very similiar to the 7720, requiring only the
addition of a calc_num_ports() function, a separate interrupt-in
endpoint callback, and some manipulation of the port pointers added to
the attach() function to correct the fact that the usbserial core
erroneously assigns the first bulk in/out endpoint pair to the serial
port (the 7715 uses these for its parallel port). There is no support
for the 7715's parallel port yet.

RTS/DTR in option_send_setup() causing a USB timeout of 5 s in any

In addition, I prepared another case for devices with interfaces which

USB: Move hcd free_dev call into usb_disconnect to fix oops
USB: Move hcd free_dev call into usb_disconnect
I found a way to oops the kernel:
1. Open a USB device through devio.
2. Remove the hcd module in the host kernel.
3. Close the devio file descriptor.
The problem is that closing the file descriptor does usb_release_dev
as it is the last reference. usb_release_dev then tries to invoke
the hcd free_dev function (or rather dereferencing the hcd driver
struct). This causes an oops as the hcd driver has already been
unloaded so the struct is gone.
This patch tries to fix this by bringing the free_dev call earlier
and into usb_disconnect. I have verified that repeating the
above steps no longer crashes with this patch applied.

This occurs because an interrupt scans uhci->skelqh, which is
being freed. We do the right thing: disable the interrupts in the
device, and do not do any processing if the interrupt is shared
with other source, but it's possible that another CPU gets
delayed somewhere (e.g. loops) until we started freeing.
The agreed-upon solution is to wait for interrupts to play out
before proceeding. No other bareers are neceesary.
A backport of this patch was tested on a 2.6.18 based kernel.
Testing of 2.6.32-based kernels is under way, but it takes us
forever (months) to turn this around. So I think it's a good
patch and we should keep it.

USB: convert to the runtime PM framework
This patch (as1329) converts the USB stack over to the PM core's
runtime PM framework. This involves numerous changes throughout
usbcore, especially to hub.c and driver.c. Perhaps the most notable
change is that CONFIG_USB_SUSPEND now depends on CONFIG_PM_RUNTIME
instead of CONFIG_PM.
Several fields in the usb_device and usb_interface structures are no
longer needed. Some code which used to depend on CONFIG_USB_PM now
depends on CONFIG_USB_SUSPEND (requiring some rearrangement of header
files).
The only visible change in behavior should be that following a system
sleep (resume from RAM or resume from hibernation), autosuspended USB
devices will be resumed just like everything else. They won't remain
suspended. But if they aren't in use then they will naturally
autosuspend again in a few seconds.

This patch (as1327) changes the way negative autosuspend delays

usb_autoresume_device() to increment the usage counter when a negative
delay is set, and by using usb_autosuspend_device() to decrement the

USB: implement usb_enable_autosuspend
This patch (as1326) adds usb_enable_autosuspend() and
usb_disable_autosuspend() routines for use by drivers. If a driver
knows that its device can handle suspends and resumes correctly, it
can enable autosuspend all by itself. This is equivalent to the user
writing "auto" to the device's power/level attribute.
The implementation differs slightly from what it used to be. Now
autosuspend is disabled simply by doing usb_autoresume_device() (to
increment the usage counter) and enabled by doing
usb_autosuspend_device() (to decrement the usage counter).
The set_level() attribute method is updated to use the new routines,
and the USB Power-Management documentation is updated.
The patch adds a usb_enable_autosuspend() call to the hub driver's
probe routine, allowing the special-case code for hubs in quirks.c to

mainly it's meant to make the locking more uniform.
The most tricky part of the patch involves changes to usbdev_open().
To avoid an ABBA locking problem, it was necessary to reduce the
region protected by usbfs_mutex. Since that mutex now protects only
against simultaneous open and remove, this posed no difficulty -- its
scope was larger than necessary.
And it turns out that usbfs_mutex is no longer needed in
usbdev_release() at all. The list of usbfs "ps" structures is now

usb: host: ehci: adding regulator framework in ehci-omap.c driver.
OMAP3 has three HS USB ports so it can have three different regulator
for each PHY connected to each port.
Currently these regulators are assumed to be optional and driver doesn't
fail but continue with the initialization if it doesn't get any regulators.
Regulator supply names has to be mapped in board files as 'hsusbN' where
'N' is port number and can be {0, 1 ,2}.

usb: musb: Fix cppi_channel_abort() function to handle Tx abort correctly
This patch fixes the Tx abort/teardown logic. We now wait for the teardown
completion interrupt and acknowledge the same by setting the tx_complete
register to 0.
This change is needed to ensure that abort processing works on DM365 platform.
Without this change after completion of abort processing the system is
overwhelmed with continuous stream of abort interrupts.
This change has been tested on all CPPI3.x platforms (DM644x, DM646x, DM35x,
DM36x).

usb: musb: workaround toggle bug when doing bulk transfer after isoc
This patch implements the work around for a Mentor controller related
bug where it's observed a BULK Tx toggle error on the bus when a
BULK IO gets scheduled on an endpoint that was earlier used for
handling ISOC transaction and needed to start on 1 toggle. When such
a situation arises even if the TXCSR toggle bits are programmed
correctly by the musb driver the data gets transmitted with 0 toggle
which leads to toggle error on the bus and the BULK transaction fails.
In case of MSC write, the device gets reset by the Host.
This Mentor bug is observed on almost all Mentor versions (1.3, 1.5,
1.8). Confirmed on DM644x, DM355, DM365, OMAPL13x platforms.

usb: musb: workaround MUSB DMA_INTR sometimes reads zero
MUSB DMA_INTR register may sometimes read zero when infact there
was a pending interrupt. Workaround this by reading the DMA_COUNT
values for all enabled channels when this condition occurs.
Flag these channels as the ones needing to be serviced.
Additionally, the absence of a debug print meant we would never
catch a spurious DMA interrupt in MUSB. So this patch adds a
debug print in the IRQ handler.
