+* Allwinner sun8i EMAC ethernet controller
+
+Required properties:
+- compatible: "allwinner,sun8i-a83t-emac", "allwinner,sun8i-h3-emac",
+		or "allwinner,sun50i-a64-emac"
List one per line.
ok
quoted
+- reg: address and length of the register sets for the device.
+- reg-names: should be "emac" and "syscon", matching the register sets
+- interrupts: interrupt for the device
+- clocks: A phandle to the reference clock for this device
+- clock-names: should be "ahb"
+- resets: A phandle to the reset control for this device
+- reset-names: should be "ahb"
+- phy-mode: See ethernet.txt
+- phy or phy-handle: See ethernet.txt
+- #address-cells: shall be 1
+- #size-cells: shall be 0
+
+"allwinner,sun8i-h3-emac" also requires:
+- clocks: an extra phandle to the reference clock for the EPHY
+- clock-names: an extra "ephy" entry matching the clocks property
+- resets: an extra phandle to the reset control for the EPHY
+- resets-names: an extra "ephy" entry matching the resets property
+
+See ethernet.txt in the same directory for generic bindings for ethernet
+controllers.
+
+The device node referenced by "phy" or "phy-handle" should be a child node
+of this node. See phy.txt for the generic PHY bindings.
+
+Optional properties:
+- phy-supply: phandle to a regulator if the PHY needs one
+- phy-io-supply: phandle to a regulator if the PHY needs a another one for I/O.
+		 This is sometimes found with RGMII PHYs, which use a second
+		 regulator for the lower I/O voltage.
I previously said these should go in the phy node, and you said you 
would remove them.

Rob
Sorry, I forgot to remove them.
I have removed them now.

Thanks
