Kernel-4.18.0-80.el8_rockchip-usb-phy

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>;
    };
};

};
