-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>;
- };
- };
-};
