1	* Renesas Electronics SH EtherMAC
2	
3	This file provides information on what the device node for the SH EtherMAC
4	interface contains.
5	
6	Required properties:
7	- compatible: "renesas,gether-r8a7740" if the device is a part of R8A7740 SoC.
8		      "renesas,ether-r8a7743"  if the device is a part of R8A7743 SoC.
9		      "renesas,ether-r8a7745"  if the device is a part of R8A7745 SoC.
10		      "renesas,ether-r8a7778"  if the device is a part of R8A7778 SoC.
11		      "renesas,ether-r8a7779"  if the device is a part of R8A7779 SoC.
12		      "renesas,ether-r8a7790"  if the device is a part of R8A7790 SoC.
13		      "renesas,ether-r8a7791"  if the device is a part of R8A7791 SoC.
14		      "renesas,ether-r8a7793"  if the device is a part of R8A7793 SoC.
15		      "renesas,ether-r8a7794"  if the device is a part of R8A7794 SoC.
16		      "renesas,ether-r7s72100" if the device is a part of R7S72100 SoC.
17	- reg: offset and length of (1) the E-DMAC/feLic register block (required),
18	       (2) the TSU register block (optional).
19	- interrupts: interrupt specifier for the sole interrupt.
20	- phy-mode: see ethernet.txt file in the same directory.
21	- phy-handle: see ethernet.txt file in the same directory.
22	- #address-cells: number of address cells for the MDIO bus, must be equal to 1.
23	- #size-cells: number of size cells on the MDIO bus, must be equal to 0.
24	- clocks: clock phandle and specifier pair.
25	- pinctrl-0: phandle, referring to a default pin configuration node.
26	
27	Optional properties:
28	- interrupt-parent: the phandle for the interrupt controller that services
29			    interrupts for this device.
30	- pinctrl-names: pin configuration state name ("default").
31	- renesas,no-ether-link: boolean, specify when a board does not provide a proper
32				 Ether LINK signal.
33	- renesas,ether-link-active-low: boolean, specify when the Ether LINK signal is
34					 active-low instead of normal active-high.
35	
36	Example (Lager board):
37	
38		ethernet@ee700000 {
39			compatible = "renesas,ether-r8a7790";
40			reg = <0 0xee700000 0 0x400>;
41			interrupt-parent = <&gic>;
42			interrupts = <0 162 IRQ_TYPE_LEVEL_HIGH>;
43			clocks = <&mstp8_clks R8A7790_CLK_ETHER>;
44			phy-mode = "rmii";
45			phy-handle = <&phy1>;
46			pinctrl-0 = <&ether_pins>;
47			pinctrl-names = "default";
48			renesas,ether-link-active-low;
49			#address-cells = <1>;
50			#size-cells = <0>;
51	
52			phy1: ethernet-phy@1 {
53				reg = <1>;
54				interrupt-parent = <&irqc0>;
55				interrupts = <0 IRQ_TYPE_LEVEL_LOW>;
56				pinctrl-0 = <&phy1_pins>;
57				pinctrl-names = "default";
58			};
59		};
