+APM X-Gene SoC Ethernet nodes
+
+Ethernet nodes are defined to describe on-chip ethernet interfaces in
+APM X-Gene SoC.
+
+Required properties:
+- compatible           : Should be "apm,xgene-enet"
+- reg                  : First resource is the ethernet base register set
+                         Second resource is the ring base register set
+                         Third resource is the ring command register set
+- interrupts           : Ethernet main interrupt
+- clocks               : Reference to the clock entry.
+- local-mac-address    : Ethernet MAC address.
+- phy-addr             : Ethernet MII phy address.
+- phy-mode             : Ethernet MII mode.
+
+Optional properties:
+- status               : Should be "ok" or "disabled" for enabled/disabled.
+                         Default is "ok".
+
+Example:
+       menetclk: menetclk {
+               compatible = "apm,xgene-device-clock";
+               clock-output-names = "menetclk";
+               status = "ok";
+       };
+
+       menet: ethernet@17020000 {
+               compatible = "apm,xgene-enet";
+               status = "disabled";
+               reg = <0x0 0x17020000 0x0 0xd100>,
+                     <0x0 0X17030000 0x0 0X400>,
+                     <0x0 0X10000000 0x0 0X200>;
+               interrupts = <0x0 0x3c 0x4>;
+               clocks = <&menetclk 0>;
+               local-mac-address = [00 01 73 00 00 01];
+               phy-addr = <3>;

An Ethernet PHY node needs to follow the ePAPR recommended
representation, which is not this one. Please refer to
Documentation/devicetree/bindinsg/net/phy.txt for examples on how to
do this properly.

Okay.  I will change the dts to use phy-handle property and remove
phy-addr.
