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
34The MAC address will be determined using the optional properties
35defined in ethernet.txt.
36
37Required subnode:
38 - mdio: A container for child nodes representing phy nodes.
39         See phy.txt in the same directory.

41Example:
42
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	};
