[PATCH] dt-bindings: phy: Convert marvell,comphy-cp110 to DT schema

From: Rob Herring (Arm)
Date: Sat Jun 07 2025 - 17:27:25 EST

Convert the Marvell CP110 combo PHY binding to DT schema format. It's a
straight forward conversion.

-MVEBU comphy drivers
---------------------
-
-COMPHY controllers can be found on the following Marvell MVEBU SoCs:
-* Armada 7k/8k (on the CP110)
-* Armada 3700
-It provides a number of shared PHYs used by various interfaces (network, SATA,
-USB, PCIe...).
-
-Required properties:
-
-- compatible: should be one of:
- * "marvell,comphy-cp110" for Armada 7k/8k
- * "marvell,comphy-a3700" for Armada 3700
-- reg: should contain the COMPHY register(s) location(s) and length(s).
- * 1 entry for Armada 7k/8k
- * 4 entries for Armada 3700 along with the corresponding reg-names
- properties, memory areas are:
- * Generic COMPHY registers
- * Lane 1 (PCIe/GbE)
- * Lane 0 (USB3/GbE)
- * Lane 2 (SATA/USB3)
-- marvell,system-controller: should contain a phandle to the system
- controller node (only for Armada 7k/8k)
-- #address-cells: should be 1.
-- #size-cells: should be 0.
-
-Optional properlties:
-
-- clocks: pointers to the reference clocks for this device (CP110 only),
- consequently: MG clock, MG Core clock, AXI clock.
-- clock-names: names of used clocks for CP110 only, must be :
- "mg_clk", "mg_core_clk" and "axi_clk".
-
-A sub-node is required for each comphy lane provided by the comphy.
-
-Required properties (child nodes):
-
-- reg: COMPHY lane number.
-- #phy-cells : from the generic PHY bindings, must be 1. Defines the
- input port to use for a given comphy lane.
-
-Examples:
-
- CP11X_LABEL(comphy): phy@120000 {
- compatible = "marvell,comphy-cp110";
- reg = <0x120000 0x6000>;
- marvell,system-controller = <&CP11X_LABEL(syscon0)>;
- clocks = <&CP11X_LABEL(clk) 1 5>, <&CP11X_LABEL(clk) 1 6>,
- <&CP11X_LABEL(clk) 1 18>;
- clock-names = "mg_clk", "mg_core_clk", "axi_clk";
- #address-cells = <1>;
- #size-cells = <0>;
-
- CP11X_LABEL(comphy0): phy@0 {
- reg = <0>;
- #phy-cells = <1>;
- };
-
- CP11X_LABEL(comphy1): phy@1 {
- reg = <1>;
- #phy-cells = <1>;
- };
- };
-
- comphy: phy@18300 {
- compatible = "marvell,comphy-a3700";
- reg = <0x18300 0x300>,
- <0x1F000 0x400>,
- <0x5C000 0x400>,
- <0xe0178 0x8>;
- reg-names = "comphy",
- "lane1_pcie_gbe",
- "lane0_usb3_gbe",
- "lane2_sata_usb3";
- #address-cells = <1>;
- #size-cells = <0>;
