This patchset adds support for USB on Amlogic A1 SoCs. This patchset is composed with : - bindings of the PHY - bindings of the USB Control Glue - PHY Driver - USB Control Glue driver - dts of the PHY - dts of the USB Controller The Amlogic A1 USB Complex is composed of : - 1 DWC3 USB controller for USB2 Host functionality - 1 USB2 PHY for USB2 Host functionality The USB Control Glue setups the clocks and the reset about DWC3 USB controller, and binds to the USB2 PHY. It also configures the 8bit UTMI interfaces for the USB2 PHY, including setting USB2 phy mode. The USB2 PHY driver initializes the phy analog settings, phy PLL setup and phy tuning. This patchset is based on A1 clock/power domain/reset series at [0].
