Dear Amit Virdi,
Support for designware USB device controller (UDC) exists in the u-boot for SPEAr platform. This patchset makes the driver more generic so that it can be used across multiple platforms.
V2:
- Configure the gadget in HS only if CONFIG_USBD_HS is defined
- Made local functions static in a separate commit
- In "Fix memory nonalignment issue" used memcpy instead of copying byte-by-byte
- Define the HS_PACKET_SIZE unconditionally
V1:
- Added support for designware UDC in a more generic way

Shiraz Hashim (1): USB:gadget:designware Fix memory nonalignment issue
Vipin KUMAR (3): USB:gadget:designware USB device controller (UDC) implementation USB:gadget:designware Device controller bugfixes USB:gadget:designware Support high speed
