1	* Synopsys ARC EMAC 10/100 Ethernet driver (EMAC)
2	
3	Required properties:
4	- compatible: Should be "snps,arc-emac"
5	- reg: Address and length of the register set for the device
6	- interrupts: Should contain the EMAC interrupts
7	- max-speed: see ethernet.txt file in the same directory.
8	- phy: see ethernet.txt file in the same directory.
9	
10	Clock handling:
11	The clock frequency is needed to calculate and set polling period of EMAC.
12	It must be provided by one of:
13	- clock-frequency: CPU frequency.
14	- clocks: reference to the clock supplying the EMAC.
15	
16	Child nodes of the driver are the individual PHY devices connected to the
17	MDIO bus. They must have a "reg" property given the PHY address on the MDIO bus.
18	
19	Examples:
20	
21		ethernet@c0fc2000 {
22			compatible = "snps,arc-emac";
23			reg = <0xc0fc2000 0x3c>;
24			interrupts = <6>;
25			mac-address = [ 00 11 22 33 44 55 ];
26	
27			clock-frequency = <80000000>;
28			/* or */
29			clocks = <&emac_clock>;
30	
31			max-speed = <100>;
32			phy = <&phy0>;
33	
34			#address-cells = <1>;
35			#size-cells = <0>;
36			phy0: ethernet-phy@0 {
37				reg = <1>;
38			};
39		};
