Kernel-4.18.0-80.el8_hisilicon-hns-mdio

Hisilicon MDIO bus controller

Properties:

• compatible: can be one of:
  “hisilicon,hns-mdio”
  “hisilicon,mdio”
  “hisilicon,hns-mdio” is recommended to be used for hip05 and later SOCs,
  while “hisilicon,mdio” is optional for backwards compatibility only on
  hip04 Soc.
• reg: The base address of the MDIO bus controller register bank.
• #address-cells: Must be <1>.
• #size-cells: Must be <0>. MDIO addresses have no size component.

Typically an MDIO bus might have several children.

Example:
mdio@803c0000 {
#address-cells = <1>;
#size-cells = <0>;
compatible = “hisilicon,hns-mdio”,”hisilicon,mdio”;
reg = <0x0 0x803c0000 0x0 0x10000>;
