[U-Boot] [PATCH v2 0/2] usb: gadget: fotg210: workaround & new hardware support

[Kuo-Jung Su]

From: Kuo-Jung Su <dantesu at faraday-tech.com>

1. It's known that EP0 fifo empty indication is not reliable, an extra delay
   is necessary to avoid data corruption while handling packets with size
   greater than 64 bytes.

2. Since hardware revision 1.11.0, some fields of interrupt status registers
   are now write-1-clear.

Changes for v2:
	- usb: gadget: fotg210: add w1c interrupt status support:
	  By writting 1 then 0 to get rid of the use of
	  CONFIG_USB_GADGET_FOTG210_ISRW1C.
	  Thanks for Marek's comments.
	- usb: gadget: fotg210: EP0 fifo empty indication is non-reliable
	  udelay_masked() -> udelay(), and patch comment updates.
