+* 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: See ethernet.txt file in the same directory
+- phy-mode: See ethernet.txt file in the same directory
+
+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>,
+ <0 0xe0780000 0 0x80000>;
+ interrupt-parent = <&gic>;
+ interrupts = <0 325 4>;
+ clocks = <&xgbe_clk>;
+ clock-names = "dma_clk";
+ phy-handle = <&phy>;
+ phy-mode = "xgmii";
+ mac-address = [ 02 a1 a2 a3 a4 a5 ];
+ };
