1	* Cadence MACB/GEM Ethernet controller
2	
3	Required properties:
4	- compatible: Should be "cdns,[<chip>-]{macb|gem}"
5	  Use "cdns,at91rm9200-emac" Atmel at91rm9200 SoC.
6	  Use "cdns,at91sam9260-macb" for Atmel at91sam9 SoCs or the 10/100Mbit IP
7	  available on sama5d3 SoCs.
8	  Use "cdns,np4-macb" for NP4 SoC devices.
9	  Use "cdns,at32ap7000-macb" for other 10/100 usage or use the generic form: "cdns,macb".
10	  Use "cdns,pc302-gem" for Picochip picoXcell pc302 and later devices based on
11	  the Cadence GEM, or the generic form: "cdns,gem".
12	  Use "atmel,sama5d2-gem" for the GEM IP (10/100) available on Atmel sama5d2 SoCs.
13	  Use "atmel,sama5d3-gem" for the Gigabit IP available on Atmel sama5d3 SoCs.
14	  Use "atmel,sama5d4-gem" for the GEM IP (10/100) available on Atmel sama5d4 SoCs.
15	  Use "cdns,zynq-gem" Xilinx Zynq-7xxx SoC.
16	  Use "cdns,zynqmp-gem" for Zynq Ultrascale+ MPSoC.
17	  Or the generic form: "cdns,emac".
18	- reg: Address and length of the register set for the device
19	- interrupts: Should contain macb interrupt
20	- phy-mode: See ethernet.txt file in the same directory.
21	- clock-names: Tuple listing input clock names.
22		Required elements: 'pclk', 'hclk'
23		Optional elements: 'tx_clk'
24	- clocks: Phandles to input clocks.
25	
26	Optional properties for PHY child node:
27	- reset-gpios : Should specify the gpio for phy reset
28	- magic-packet : If present, indicates that the hardware supports waking
29	  up via magic packet.
30	
31	Examples:
32	
33		macb0: ethernet@fffc4000 {
34			compatible = "cdns,at32ap7000-macb";
35			reg = <0xfffc4000 0x4000>;
36			interrupts = <21>;
37			phy-mode = "rmii";
38			local-mac-address = [3a 0e 03 04 05 06];
39			clock-names = "pclk", "hclk", "tx_clk";
40			clocks = <&clkc 30>, <&clkc 30>, <&clkc 13>;
41			ethernet-phy@1 {
42				reg = <0x1>;
43				reset-gpios = <&pioE 6 1>;
44			};
45		};
