[PATCH net] dt-bindings: net: Convert UniPhier AVE4 controller to json-schema

From: Kunihiko Hayashi
Date: Tue Apr 28 2020 - 02:31:35 EST

Convert the UniPhier AVE4 controller binding to DT schema format.
This changes phy-handle property to required.

-* Socionext AVE ethernet controller
-
-This describes the devicetree bindings for AVE ethernet controller
-implemented on Socionext UniPhier SoCs.
-
-Required properties:
- - compatible: Should be
- - "socionext,uniphier-pro4-ave4" : for Pro4 SoC
- - "socionext,uniphier-pxs2-ave4" : for PXs2 SoC
- - "socionext,uniphier-ld11-ave4" : for LD11 SoC
- - "socionext,uniphier-ld20-ave4" : for LD20 SoC
- - "socionext,uniphier-pxs3-ave4" : for PXs3 SoC
- - reg: Address where registers are mapped and size of region.
- - interrupts: Should contain the MAC interrupt.
- - phy-mode: See ethernet.txt in the same directory. Allow to choose
- "rgmii", "rmii", "mii", or "internal" according to the PHY.
- The acceptable mode is SoC-dependent.
- - phy-handle: Should point to the external phy device.
- See ethernet.txt file in the same directory.
- - clocks: A phandle to the clock for the MAC.
- For Pro4 SoC, that is "socionext,uniphier-pro4-ave4",
- another MAC clock, GIO bus clock and PHY clock are also required.
- - clock-names: Should contain
- - "ether", "ether-gb", "gio", "ether-phy" for Pro4 SoC
- - "ether" for others
- - resets: A phandle to the reset control for the MAC. For Pro4 SoC,
- GIO bus reset is also required.
- - reset-names: Should contain
- - "ether", "gio" for Pro4 SoC
- - "ether" for others
- - socionext,syscon-phy-mode: A phandle to syscon with one argument
- that configures phy mode. The argument is the ID of MAC instance.
-
-The MAC address will be determined using the optional properties
-defined in ethernet.txt.
-
-Required subnode:
- - mdio: A container for child nodes representing phy nodes.
- See phy.txt in the same directory.
-
-Example:
-
- ether: ethernet@65000000 {
- compatible = "socionext,uniphier-ld20-ave4";
- reg = <0x65000000 0x8500>;
- interrupts = <0 66 4>;
- phy-mode = "rgmii";
- phy-handle = <&ethphy>;
- clock-names = "ether";
- clocks = <&sys_clk 6>;
- reset-names = "ether";
- resets = <&sys_rst 6>;
- socionext,syscon-phy-mode = <&soc_glue 0>;
- local-mac-address = [00 00 00 00 00 00];
-
- mdio {
- #address-cells = <1>;
- #size-cells = <0>;
-
- ethphy: ethphy@1 {
- reg = <1>;
- };
- };
- };
