Hi,
this series enables USB support on the H6 boards. This is mostly just adding some missing pieces here and there, the actual controller and PHY are very similar to the previous ones, if not identical. This is for the 2.0 ports only at the moment, USB 3.0 will be done later (started porting Icenowy's Linux driver). The Pine H64 shares a similar problem as the Pine64+ boards regarding the upper USB port. To enable this port, we need the first patch from the series [1] fixing this issue on the A64 boards.
Patch 1 is a drive-by patch to bring SUNXI_GPIO to Kconfig, as this was lingering in one of my branches for a while. Patch 2 enables GPIO support for the H6, as this is needed for the Pine H64 to enable the VBUS regulator. Patch 3 adds the clock and reset gates mappings for the USB controller and the PHY, the values are taken from the manual and verified against Linux. Patch 4 adds some code to the PHY driver to skip over not implemented PHYs, as the H6 uses a PHY0/PHY3 combination in the DT. Patch 5 then eventually enables USB in the existing defconfigs. Patch 6 adds the .dts fixes required to get the upper USB port to work on the Pine H64.
Clément, can you please verify that this works for the Beelink box? I guess the USB 2.0 port is probably the OTG one, so this setup would look somewhat similar to the PineH64, which would allow you to copy the USB DT nodes from there.
Cheers, Andre.
