Let me know of any feedback and suggestions.
Known Issues:
DWC3 is not enumerating consistently.
Kishon Vijay Abraham I (13):
include: linux: preparation for porting dwc3 from linux kernel
usb: gadget: udc-core: Add minimal udc-core from linux kernel
ARM: DRA7: Enable clocks for USB OTGSS
In order to support multiple USB device controllers in uboot,
udc-core is needed. udc-core also helps to cleanly link the USB peripheral
driver with the gadget driver. Hence Ported minimal udc-core from
linux kernel.

Bounce buffer is used for transferring requests which is not maxpacket

While the actual fix for this should be using two chained TRBs to handle

Changed the header files included in core.h and io.h to the u-boot header
files so that these files can be included in other dwc3 source files and
be compiled in uboot. Also added otg.h which has the defines for dr_mode.

dwc3 can do only max packet aligned transfers. So in case request length
is not max packet aligned and is bigger than DWC3_EP0_BOUNCE_SIZE
two chained TRBs is required to handle the transfer.

DWC3 hangs on OUT requests smaller than maxpacket size,
so HACK the request length to be at least equal to maxpacket size.
Curious to know using which gadget this issue was seen.
