Subject: [PATCH net] dt-bindings: net: Convert UniPhier AVE4 controller to json-schema
Date:   Tue, 28 Apr 2020 15:31:22 +0900
Message-Id: <1588055482-13012-1-git-send-email-hayashi.kunihiko@socionext.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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>;
-			};
-		};
-	};
