Subject: Re: [PATCH 2/4] dt-bindings: phy: rockchip: USB2: Add compatible for
 rk3568

Hi Benjamin,

The '#phy-cells' in [PATCH 1/4] are already gone.
The nodename is renamed to pattern "usb2phy@[0-9a-f]+$".
phy-rockchip-inno-usb2.yaml is now also part of grf.yaml, so must take
care of both.

>From rk3568.dtsi:

	usb2phy0_grf: syscon@...a0000 {
		compatible = "rockchip,rk3568-usb2phy-grf", "syscon";
		reg = <0x0 0xfdca0000 0x0 0x8000>;
	};

	usb2phy1_grf: syscon@...a8000 {
		compatible = "rockchip,rk3568-usb2phy-grf", "syscon";
		reg = <0x0 0xfdca8000 0x0 0x8000>;
	};

	usb2phy0: usb2phy@...a0000 {
		compatible = "rockchip,rk3568-usb2phy";
		reg = <0x0 0xfe8a0000 0x0 0x10000>;
		interrupts = <GIC_SPI 135 IRQ_TYPE_LEVEL_HIGH>;
		clocks = <&pmucru CLK_USBPHY0_REF>;
		clock-names = "phyclk";
		#clock-cells = <0>;
		assigned-clocks = <&cru USB480M>;
		assigned-clock-parents = <&usb2phy0>;
		clock-output-names = "usb480m_phy";
		rockchip,usbgrf = <&usb2phy0_grf>;
		status = "disabled";

		u2phy0_host: host-port {
			#phy-cells = <0>;
			status = "disabled";
		};

		u2phy0_otg: otg-port {
			#phy-cells = <0>;
			status = "disabled";
		};
	};

	usb2phy1: usb2phy@...b0000 {
		compatible = "rockchip,rk3568-usb2phy";
		reg = <0x0 0xfe8b0000 0x0 0x10000>;
		interrupts = <GIC_SPI 136 IRQ_TYPE_LEVEL_HIGH>;
		clocks = <&pmucru CLK_USBPHY1_REF>;
		clock-names = "phyclk";
		#clock-cells = <0>;
		rockchip,usbgrf = <&usb2phy1_grf>;
		status = "disabled";

		u2phy1_host: host-port {
			#phy-cells = <0>;
			status = "disabled";
		};

		u2phy1_otg: otg-port {
			#phy-cells = <0>;
			status = "disabled";
		};
	};

rockchip,rk3568-usb2phy-grf must also be added to grf.yaml.

See linux-next.
