- 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.
- 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.
