Seems OK.
Also, IIUC, I think if we ever want to support dual-role/OTG, we need an
extcon reference in the USB2/OTG PHY that serves these ports too. i.e.,
u2phy0 and u2phy1? Notably, the PHY driver supports the extcon
properties, but it's not documented in
Documentation/devicetree/bindings/phy/phy-rockchip-inno-usb2.txt yet (we
should probably get that fixed).
So, anyway, maybe the above isn't a blocker for this patch. Just noticed
it while reading. Assuming the driver stuff falls into place:
