The newer SoCs (rk3366, rk3399) of Rock-chip take a different usb-phy IP block than rk3288 and before, and most of phy-related registers are also different from the past, so a new phy driver is required necessarily.
These series patches add phy-rockchip-inno-usb2.c and the corresponding documentation.
