1* Socionext AVE ethernet controller
2
3This describes the devicetree bindings for AVE ethernet controller
4implemented on Socionext UniPhier SoCs.

6Required properties:
7 - compatible: Should be
8	- "socionext,uniphier-pro4-ave4" : for Pro4 SoC
9	- "socionext,uniphier-pxs2-ave4" : for PXs2 SoC
10	- "socionext,uniphier-ld11-ave4" : for LD11 SoC
11	- "socionext,uniphier-ld20-ave4" : for LD20 SoC
12	- "socionext,uniphier-pxs3-ave4" : for PXs3 SoC
13 - reg: Address where registers are mapped and size of region.
14 - interrupts: Should contain the MAC interrupt.
15 - phy-mode: See ethernet.txt in the same directory. Allow to choose
16	"rgmii", "rmii", "mii", or "internal" according to the PHY.
17	The acceptable mode is SoC-dependent.
18 - phy-handle: Should point to the external phy device.
19	See ethernet.txt file in the same directory.
20 - clocks: A phandle to the clock for the MAC.
21	For Pro4 SoC, that is "socionext,uniphier-pro4-ave4",
22	another MAC clock, GIO bus clock and PHY clock are also required.
23 - clock-names: Should contain
24	- "ether", "ether-gb", "gio", "ether-phy" for Pro4 SoC
25	- "ether" for others
26 - resets: A phandle to the reset control for the MAC. For Pro4 SoC,
27	GIO bus reset is also required.
28 - reset-names: Should contain
29	- "ether", "gio" for Pro4 SoC
30	- "ether" for others
31 - socionext,syscon-phy-mode: A phandle to syscon with one argument
32	that configures phy mode. The argument is the ID of MAC instance.
33
34Optional properties:
35 - local-mac-address: See ethernet.txt in the same directory.
36
37Required subnode:
38 - mdio: A container for child nodes representing phy nodes.
39         See phy.txt in the same directory.

43	ether: ethernet@65000000 {
44		compatible = "socionext,uniphier-ld20-ave4";
45		reg = <0x65000000 0x8500>;
46		interrupts = <0 66 4>;
47		phy-mode = "rgmii";
48		phy-handle = <&ethphy>;
49		clock-names = "ether";
50		clocks = <&sys_clk 6>;
51		reset-names = "ether";
52		resets = <&sys_rst 6>;
53		socionext,syscon-phy-mode = <&soc_glue 0>;
54		local-mac-address = [00 00 00 00 00 00];
55
56		mdio {
57			#address-cells = <1>;
58			#size-cells = <0>;
59
60			ethphy: ethphy@1 {
61				reg = <1>;
62			};
63		};
64	};
