First two patches are preparatory work. 3rd and 4th introduce helper functions. Patch 5 contains the core changes. Patch 6 is cleanup.
The patch has been tested on RPi 1 B with several full speed and low speed devices. All devices enumerated successfully, with good output from "usb info". High speed devices, e.g. the SMSC9514 ethernet and mass storage devices still work.
Neither CONFIG_DM_USB nor LS/FS devices directly connected to the root hub/hc have been tested, although both should be handled by the patches.
The series, Tested-by: Stephen Warren swarren@wwwdotorg.org
It's not perfect with the USB keyboards that I have (there are lots of rapid extra keyboard repeats), but it basically does work and so I think warrants the Tested-by. The extra repeats might be due to the strange hacks I put into dwc2.c:_submit_int_msg() to try and handle the NAKing of HID requests until the polling period has expired.
