ROCKCHIP USB2 PHY Required properties: - compatible: matching the soc type, one of "rockchip,rk3066a-usb-phy" "rockchip,rk3188-usb-phy" "rockchip,rk3288-usb-phy" - #address-cells: should be 1 - #size-cells: should be 0 Deprecated properties: - rockchip,grf : phandle to the syscon managing the "general register files" - phy should be a child of the GRF instead Sub-nodes: Each PHY should be represented as a sub-node. Sub-nodes required properties: - #phy-cells: should be 0 - reg: PHY configure reg address offset in GRF "0x320" - for PHY attach to OTG controller "0x334" - for PHY attach to HOST0 controller "0x348" - for PHY attach to HOST1 controller Optional Properties: - clocks : phandle + clock specifier for the phy clocks - clock-names: string, clock name, must be "phyclk" - #clock-cells: for users of the phy-pll, should be 0 - reset-names: Only allow the following entries: - phy-reset - resets: Must contain an entry for each entry in reset-names. - vbus-supply: power-supply phandle for vbus power source Example: grf: syscon@ff770000 { compatible = "rockchip,rk3288-grf", "syscon", "simple-mfd"; ... usbphy: phy { compatible = "rockchip,rk3288-usb-phy"; #address-cells = <1>; #size-cells = <0>; usbphy0: usb-phy0 { #phy-cells = <0>; reg = <0x320>; }; }; };
