[PATCH 00/36] usb: gadget: f_tcm: Enhance UASP driver

[Thinh Nguyen <Thinh.Nguyen@synopsys.com>]

The Linux UASP gadget driver is incomplete and remained broken for a long time.
It was not implemented for performance either. This series adds some of the
required features for the UASP driver to work. It also makes some fixes to the
target core.

Please note that the f_tcm is far from a good state. It needs better error
recovery, error reports, more cleanup, and the ability to handle various
required commands.

Also please note that I try to juggle between checkpatch warnings and code
style consistency. As a result, there maybe some minor checkpatch warnings.

Hopefully this can help jumpstart the UASP driver. Please test it out.

This was tested against UASP CV and DWC_usb3x controller.

Thanks!
