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.

This patch add USB client support Marvell PXA9xx/PXA168 chips. The USB
controller in PXA9xx/PXA168 is a High-Speed OTG controller. The available
endpoints is different between PXA9xx and PXA168.
NOTE:
It is the first version of Marvell PXA9xx/PXA168 USB controller driver.
The support for OTG mode will be added in later patch.
PXA9xx and PXA168 has integrated UTMI PHY in the chips. The initialization
for the PHY is a little different between PXA9xx and PXA168.

Several of the EHCI glue drivers either predate or were merged in the
same timeframe as API changes at the USB core level, resulting in some
missing endpoint_reset and clear_tt_buffer_complete callbacks.
This fixes up all of ehci-atmel, mxc, w90x900, and xilinx-of to tie in
the new helpers, which brings them in line with everyone else.

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.

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.

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.

Update the ehci-omap glue layer to support the controller in the
OMAP4. Major differences from OMAP3 is that the OMAP4 has per-port
clocking, and supports ULPI output clocking mode. The old input
clocking mode is not supported.
Also, there are only 2 externally available ports as against 3
in the OMAP3. The third port is internally tied off and should

This patch (as1434) cleans up the uses of usb_mark_last_busy() in
usbcore. The function will be called when a device is resumed and
whenever a usage count is decremented. A call that was missing from
the hub driver is added: A hub is used whenever one of its ports gets
suspended (this prevents hubs from suspending immediately after their
last child).
In addition, the call to disable autosuspend support for new devices
by default is moved from usb_detect_quirks() (where it doesn't really
belong) into usb_new_device() along with all the other runtime-PM
initializations. Finally, an extra pm_runtime_get_noresume() is added
to prevent new devices from autosuspending while they are being
registered.

This patch (as1428) converts USB over to the new runtime-PM core
autosuspend framework. One slightly awkward aspect of the conversion
is that USB devices will now have two suspend-delay attributes: the
old power/autosuspend file and the new power/autosuspend_delay_ms
file. One expresses the delay time in seconds and the other in
milliseconds, but otherwise they do the same thing. The old attribute
can be deprecated and then removed eventually.
