  • Allwinner GMAC ethernet controller

This device is a platform glue layer for stmmac.
Please see stmmac.txt for the other unchanged properties.

Required properties:

  • compatible: Should be “allwinner,sun7i-a20-gmac”
  • clocks: Should contain the GMAC main clock, and tx clock
    The tx clock type should be “allwinner,sun7i-a20-gmac-clk”
  • clock-names: Should contain the clock names “stmmaceth”,
    and “allwinner_gmac_tx”

Optional properties:

  • phy-supply: phandle to a regulator if the PHY needs one

Examples:

gmac: ethernet@1c50000 {
    compatible = "allwinner,sun7i-a20-gmac";
    reg = <0x01c50000 0x10000>,
          <0x01c20164 0x4>;
    interrupts = <0 85 1>;
    interrupt-names = "macirq";
    clocks = <&ahb_gates 49>, <&gmac_tx>;
    clock-names = "stmmaceth", "allwinner_gmac_tx";
    phy-mode = "mii";
};
