0a2b8a0d11 usb: makefile cleanup
For all modules, change <module>-objs to <module>-y; remove
if-statements and replace with lists using the kbuild idiom; move
flags to the top of the file; and fix alignment while trying to
maintain the original scheme in each file.

None of the dependencies are modified.

319feaabb6 usb: gadget: goku_udc: Fix error path
This is based on an initial patch by Rahul Ruikar.

The goku_remove() function can be called before device_register() so it
can call device_unregister() improperly.  Also if the call to
device_register() fails we need to call put_device().

As I was changing the error handling in goku_probe(), I noticed that
the label was "done" but actually if the function succeeds we return
earlier.  I renamed the error path to "err" instead of "done."

126512e3f2 USB: add platform glue driver for FSL USB DR controller
Replace FSL USB platform code by simple platform driver for
creation of FSL USB platform devices.

The driver creates platform devices based on the information
from USB nodes in the flat device tree. This is the replacement
for old arch fsl_soc usb code removed by this patch. The driver
uses usual of-style binding, available EHCI-HCD and UDC
drivers can be bound to the created devices. The new of-style
driver additionaly instantiates USB OTG platform device, as the
appropriate USB OTG driver will be added soon.

5c836e4d58 usb gadget: composite: prevent OOPS for non-standard control request
The composite gadget will OOPS if the host sends a control request
targetted to an interface of an un-configured composite device. This patch
prevents this.

The OOPS was observed during WHQL USB CV tests. With this patch, the device
STALLs as per requirement.

Failing test case: From host do the following. I used libusb-1.0

1) Set configuration to zero.
	libusb_control_transfer(device_handle,
		0, /* standard OUT */
		0x9, /* setConfiguration */
		0, 0, NULL, 0, 0);

2) Query current configuratioan.
	libusb_control_transfer(device_handle,
		0x80, /* standard IN*/
		0x8, /* getConfiguration */
		0, 0, data, 1, 0);

3) Send the non-standard ctrl transfer targetted to interface
	libusb_control_transfer(device_handle,
		0x81, /* standard IN to interface*/
		0x6, /* getDescriptor */
		0x2300, 0, data, 0x12, 0);

ad1a8102f9 USB: gadget: composite: Better string override handling
The iManufatcurer, iProduct and iSerialNumber composite module
parameters were only used when the gadget driver registers
strings for manufacturer, product and serial number.  If the
gadget never bothered to set corresponding fields in USB device
descriptors those module parameters are ignored.

This commit makes the parameters work even if the strings ID
have not been assigned.  It also changes the way IDs are
overridden -- what IDs are overridden is now saved in
usb_composite_dev structure -- which makes it unnecessary to
modify the string tables the way previous code did.

The commit also adds a iProduct and iManufatcurer fields to the
usb_composite_device structure.  If they are set, appropriate
strings are reserved and added to device descriptor.  This makes
it unnecessary for gadget drivers to maintain code for setting
those.  If iProduct is not set it defaults to
usb_composite_device::name; if iManufatcurer is not set
a default "<system> <release> with <gadget-name>" is used.

The last thing is that if needs_serial field of
usb_composite_device is set and user failed to provided
iSerialNumber parameter a warning is issued.

9a887162be USB: uvc_v4l2: cleanup test for end of loop
We're trying to test for the the end of the loop here.  "format" is
never NULL.  We don't know what "format->fcc" is because we're past the
end of the loop and I think "fmt->fmt.pix.pixelformat" comes from the
user so we don't know what that is either.  It works, but it's cleaner
to just test to see if (i == ARRAY_SIZE(uvc_formats).

567064916e USB: gadget: file_storage: serial parameter even if not test mode
Moved the serial parameter handling code out of "#ifdef
CONFIG_USB_FILE_STORAGE_TEST".

This modifies Yann Cantin's commit "USB: Add a serial number
parameter to g_file_storage" module as per Alan Stern's request.

31ee04de7e USB: s3c-hsotg: add support for clock gating
This patch adds support for clock gating of the HS/OTG block. On S5PV210
otg gating clock is initally disabled so the driver needs to get and
enable it before it can access its registers.

S5PV210 SoCs has 2 USB PHY interfaces, both enabled by writing zero to
S3C_PHYPWR register. HS/OTG driver uses only PHY0, so do not touch bits
related to PHY1.

e50bf385bf USB: s3c-hsotg: Add support for external USB clock
The PLL that drives the USB clock supports 3 input clocks: 12, 24 and 48Mhz.
This patch adds support to the USB driver for setting the correct register bit
according to the given clock.

This depends on the following patch:
