* 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";
reg = <0 0xe1240800 0 0x00400>,
<0 0xe1250000 0 0x00060>,
<0 0xe1250080 0 0x00004>;

* 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 ];
};
