From: Kuo-Jung Su <dant...@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.
