-* 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:
-

- reset-names = "stmmaceth";
- clocks = <&ccu CLK_BUS_EMAC>;
- clock-names = "stmmaceth";
