+* Allwinner sun8i 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 one of the following string:
+ "allwinner,sun8i-a83t-emac"
+ "allwinner,sun8i-h3-emac"
+ "allwinner,sun8i-v3s-emac"
+ "allwinner,sun50i-a64-emac"
+- reg: address and length of the register for the device.
+- interrupts: interrupt for the device
+- interrupt-names: should be "macirq"
+- clocks: A phandle to the reference clock for this device
+- clock-names: should be "stmmaceth"
+- resets: A phandle to the reset control for this device
+- reset-names: should be "stmmaceth"
+- phy-mode: See ethernet.txt
+- phy-handle: See ethernet.txt
+- #address-cells: shall be 1
+- #size-cells: shall be 0
+- syscon: A phandle to the syscon of the SoC with one of the following
+ compatible string:
+ - allwinner,sun8i-h3-system-controller
+ - allwinner,sun8i-v3s-system-controller
+ - allwinner,sun50i-a64-system-controller
+ - allwinner,sun8i-a83t-system-controller
+
+Optional properties:
+- allwinner,tx-delay-ps: TX clock delay chain value in ps. Range value is 0-700. Default is 0)
+- allwinner,rx-delay-ps: RX clock delay chain value in ps. Range value is 0-3100. Default is 0)
+Both delay properties need to be a multiple of 100. They control the delay for
+external PHY.
+
+Optional properties for the following compatibles:
+ - "allwinner,sun8i-h3-emac",
+ - "allwinner,sun8i-v3s-emac":
+- allwinner,leds-active-low: EPHY LEDs are active low
+
+Required child node of emac:
+- mdio bus node: should be named mdio
+
+Required properties of the mdio node:
+- #address-cells: shall be 1
+- #size-cells: shall be 0
+
+The device node referenced by "phy" or "phy-handle" should be a child node
+of the mdio node. See phy.txt for the generic PHY bindings.
+
+Required properties of the phy node with the following compatibles:
+ - "allwinner,sun8i-h3-emac",
+ - "allwinner,sun8i-v3s-emac":
+- clocks: a phandle to the reference clock for the EPHY
+- resets: a phandle to the reset control for the EPHY
+
+Example:
+
+emac: ethernet@1c0b000 {
+ compatible = "allwinner,sun8i-h3-emac";
+ syscon = <&syscon>;
+ reg = <0x01c0b000 0x104>;
+ interrupts = <GIC_SPI 82 IRQ_TYPE_LEVEL_HIGH>;
+ interrupt-names = "macirq";
+ resets = <&ccu RST_BUS_EMAC>;
+ reset-names = "stmmaceth";
+ clocks = <&ccu CLK_BUS_EMAC>;
+ clock-names = "stmmaceth";
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ phy-handle = <&int_mii_phy>;
+ phy-mode = "mii";
+ allwinner,leds-active-low;
+ mdio: mdio {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ int_mii_phy: ethernet-phy@1 {
+ reg = <1>;
+ clocks = <&ccu CLK_BUS_EPHY>;
+ resets = <&ccu RST_BUS_EPHY>;
+ };
+ };
+};
