[PATCH] dt-bindings: phy: Convert brcm,ns2-drd-phy to DT schema
From: Rob Herring (Arm)
Date: Sat Jun 07 2025 - 17:25:21 EST
Convert the Broadcom NS2 USB2 PHY binding to DT schema format. It's a
straight forward conversion.

-BROADCOM NORTHSTAR2 USB2 (DUAL ROLE DEVICE) PHY
-
-Required properties:
- - compatible: brcm,ns2-drd-phy
- - reg: offset and length of the NS2 PHY related registers.
- - reg-names
- The below registers must be provided.
- icfg - for DRD ICFG configurations
- rst-ctrl - for DRD IDM reset
- crmu-ctrl - for CRMU core vdd, PHY and PHY PLL reset
- usb2-strap - for port over current polarity reversal
- - #phy-cells: Must be 0. No args required.
- - vbus-gpios: vbus gpio binding
- - id-gpios: id gpio binding
-
-Refer to phy/phy-bindings.txt for the generic PHY binding properties
-
-Example:
- usbdrd_phy: phy@66000960 {
- #phy-cells = <0>;
- compatible = "brcm,ns2-drd-phy";
- reg = <0x66000960 0x24>,
- <0x67012800 0x4>,
- <0x6501d148 0x4>,
- <0x664d0700 0x4>;
- reg-names = "icfg", "rst-ctrl",
- "crmu-ctrl", "usb2-strap";
- id-gpios = <&gpio_g 30 0>;
- vbus-gpios = <&gpio_g 31 0>;
- };
