1	* AMD 10GbE driver (amd-xgbe)
2	
3	Required properties:
4	- compatible: Should be "amd,xgbe-seattle-v1a"
5	- reg: Address and length of the register sets for the device
6	   - MAC registers
7	   - PCS registers
8	- interrupt-parent: Should be the phandle for the interrupt controller
9	  that services interrupts for this device
10	- interrupts: Should contain the amd-xgbe interrupt(s). The first interrupt
11	  listed is required and is the general device interrupt. If the optional
12	  amd,per-channel-interrupt property is specified, then one additional
13	  interrupt for each DMA channel supported by the device should be specified
14	- clocks:
15	   - DMA clock for the amd-xgbe device (used for calculating the
16	     correct Rx interrupt watchdog timer value on a DMA channel
17	     for coalescing)
18	   - PTP clock for the amd-xgbe device
19	- clock-names: Should be the names of the clocks
20	   - "dma_clk" for the DMA clock
21	   - "ptp_clk" for the PTP clock
22	- phy-handle: See ethernet.txt file in the same directory
23	- phy-mode: See ethernet.txt file in the same directory
24	
25	Optional properties:
26	- mac-address: mac address to be assigned to the device. Can be overridden
27	  by UEFI.
28	- dma-coherent: Present if dma operations are coherent
29	- amd,per-channel-interrupt: Indicates that Rx and Tx complete will generate
30	  a unique interrupt for each DMA channel - this requires an additional
31	  interrupt be configured for each DMA channel
32	
33	Example:
34		xgbe@e0700000 {
35			compatible = "amd,xgbe-seattle-v1a";
36			reg = <0 0xe0700000 0 0x80000>,
37			      <0 0xe0780000 0 0x80000>;
38			interrupt-parent = <&gic>;
39			interrupts = <0 325 4>,
40				     <0 326 1>, <0 327 1>, <0 328 1>, <0 329 1>;
41			amd,per-channel-interrupt;
42			clocks = <&xgbe_dma_clk>, <&xgbe_ptp_clk>;
43			clock-names = "dma_clk", "ptp_clk";
44			phy-handle = <&phy>;
45			phy-mode = "xgmii";
46			mac-address = [ 02 a1 a2 a3 a4 a5 ];
47		};
