+* AMD 10GbE PHY driver (amd-xgbe-phy)
+
+Required properties:
+- compatible: Should be "amd,xgbe-phy-seattle-v1a" and
+  "ethernet-phy-ieee802.3-c45"
+- reg: Address and length of the register sets for the device
+   - SerDes Rx/Tx registers
+   - SerDes integration registers (1/2)
+   - SerDes integration registers (2/2)
+
+Example:
+       xgbe_phy@e1240800 {
+               compatible = "amd,xgbe-phy-seattle-v1a", "ethernet-phy-ieee802.3-c45";

+* AMD 10GbE driver (amd-xgbe)
+
+Required properties:
+- compatible: Should be "amd,xgbe-seattle-v1a"
+- reg: Address and length of the register sets for the device
+   - MAC registers
+   - PCS registers
+- interrupt-parent: Should be the phandle for the interrupt controller
+  that services interrupts for this device
+- interrupts: Should contain the amd-xgbe interrupt
+- clocks: Should be the DMA clock for the amd-xgbe device (used for
+  calculating the correct Rx interrupt watchdog timer value on a DMA
+  channel for coalescing)
+- clock-names: Should be the name of the DMA clock, "dma_clk"
+- phy-handle: Should be the phandle for the associated phy
You can also reference ethernet.txt and phy.txt in the same directory
for details about 'phy-handle'.

'phy-mode' is also a required property here since you have specified a
'phy-handle' phandle to the PHY node.
+
+Optional properties:
+- mac-address: mac address to be assigned to the device. Can be overridden
+  by UEFI.
+
+Example:
+       xgbe@e0700000 {
+               compatible = "amd,xgbe-seattle-v1a";
+               reg = <0 0xe0700000 0 0x80000>,

+               interrupt-parent = <&gic>;
+               interrupts = <0 325 4>;
+               clocks = <&xgbe_clk>;
+               clock-names = "dma_clk";
+               phy-handle = <&phy>;
+               mac-address = [ 02 a1 a2 a3 a4 a5 ];
