Kernel-4.18.0-80.el8_phy-mvebu-comphy

mvebu comphy driver

A comphy controller can be found on Marvell Armada 7k/8k on the CP110. It
provides a number of shared PHYs used by various interfaces (network, sata,
usb, PCIe…).

Required properties:

• compatible: should be “marvell,comphy-cp110”
• reg: should contain the comphy register location and length.
• marvell,system-controller: should contain a phandle to the

                         system controller node.
  

• #address-cells: should be 1.
• #size-cells: should be 0.

A sub-node is required for each comphy lane provided by the comphy.

Required properties (child nodes):

• reg: comphy lane number.
• #phy-cells : from the generic phy bindings, must be 1. Defines the

           input port to use for a given comphy lane.
  

Example:

cpm_comphy: phy@120000 {
    compatible = "marvell,comphy-cp110";
    reg = <0x120000 0x6000>;
    marvell,system-controller = <&cpm_syscon0>;
    #address-cells = <1>;
    #size-cells = <0>;

    cpm_comphy0: phy@0 {
        reg = <0>;
        #phy-cells = <1>;
    };

    cpm_comphy1: phy@1 {
        reg = <1>;
        #phy-cells = <1>;
    };
};
