Felipe Balbi 784173723e usb: musb: drop musb_platform_suspend/resume
all glue layers are now fully moved to the
new setup. We are now using dev_pm_ops to
implement suspend/resume functionality and
thus, musb_platform_suspend/resume has become
deprecated and useless.

This patch drops those function pointers and
its uses.

preparing to a big refactor on musb code. We need
to be able to compile in all glue layers (or at
least all ARM-based ones) together and have a

While preparing for that, we move every glue

a struct musb_platform_ops, and make all
other functions static.

Later patches will come to allow for compiling
all glue layers together and have a working

peculiarities in a manner which doesn't affect one

Hema Kalliguddi fcf173e451 usb: musb: add names for IRQs in structure resource
Soon resource data will get automatically
populated from a set of autogenerated data
from TI's hardware database for the OMAP
platform.

Such database, might not have resources at
the expected order by the current drivers.

While we could hack in some exceptions to
that tool to generate resources in a specific
order, it seems less fragile to use the
resource name instead. That way, no matter
what order the resources are generated, the
driver still work.

Modified the OMAP, Blackfin and Davinci
architecture files to add the name of the IRQs
in the resource structures and musb driver to
use the platform_get_irq_byname() api to get
the device and dma irq numbers instead of using
the index.

during suspend state. This current limitation in suspend state shouldn't be
more than 2.5mA

Jarkko Nikula c3d6450e74 usb: otg: twl4030-usb: Fix unbalanced regulator disables at module removal
Function twl4030_usb_remove can cause unbalanced regulator disables in
twl4030_phy_power if the cable is not connected. Regulator enable/disable
calls are in balance only if the twl4030_phy_resume was called prior the
twl4030_usb_remove, that is, the cable was connected.

Fix this by checking the 'asleep' variable in twl4030_usb_remove since that
variable is used to check state in other functions.

Dan Williams 02303f7337 usb-wwan: implement TIOCGSERIAL and TIOCSSERIAL to avoid blocking close(2)
Some devices (ex ZTE 2726) simply don't respond at all when data is sent
to some of their USB interfaces.  The data gets stuck in the TTYs queue
and sits there until close(2), which them blocks because closing_wait
defaults to 30 seconds (even though the fd is O_NONBLOCK).  This is
rarely desired.  Implement the standard mechanism to adjust closing_wait
and let applications handle it how they want to.

Jesper Juhl 73f35c60d5 USB: Remove unnecessary casts of void ptr returning alloc function return values
Hi,

The [vk][cmz]alloc(_node) family of functions return void pointers which
it's completely unnecessary/pointless to cast to other pointer types since
that happens implicitly.

This patch removes such casts from drivers/usb/

Pete Zaitcev b17ea167c5 usbmon: correct length for isochronous
Usually the usbmon returns the amount of data specified in
urb->transfer_buffer_length for output submissions and urb->actual_length
for input callbacks. However, for Isochronous input transfers, this is
not enough, since the returned data buffer may contain "holes".

One easy way to fix this is to use urb->transfer_buffer_length,
but this often transfers a whole lot of unused data, so we find
how much was actually used instead.

Original patch by Márton Németh. See also kernel bug 22182.
