Kernel-4.18.0-80.el8_smsc-lan87xx

SMSC LAN87xx Ethernet PHY

Some boards require special tuning values. Configure them
through an Ethernet OF device node.

Optional properties:

• smsc,disable-energy-detect:
  If set, do not enable energy detect mode for the SMSC phy.
  default: enable energy detect mode

Examples:
smsc phy with disabled energy detect mode on an am335x based board.
&davinci_mdio {
pinctrl-names = “default”, “sleep”;
pinctrl-0 = <&davinci_mdio_default>;
pinctrl-1 = <&davinci_mdio_sleep>;

ethernetphy0: ethernet-phy@0 {
    reg = <0>;
    smsc,disable-energy-detect;
};

};
