[PATCH 0/2] Add a quirk for dwc3 driver, requred for Hikey 970 USB to work

From: Mauro Carvalho Chehab
Date: Tue Sep 08 2020 - 03:21:08 EST

This small patch series add a new quirk for the dwc3 driver. The first patch
was submitted previously to the USB mailing list:


This quirk is also present at the official Linaro's tree for Hikey 970.

Without that, the URBs produced by the USB HID driver returns -EPROTO
errors, causing an endless reset loop, on every 0.5 seconds.

Please notice that I don't have any documentation about Synopsys
dwc3 driver. So, I tried my best to document this quirk at patch 2,
but I can't add anything more specifics, as I don't have any datasheets
from such IP.
