dt-bindings: phy: Renesas R-Car Gen3 PCIe PHY bindings (4fa88cd3) · Commits · 戴 / test

This PHY is still mostly undocumented -- the only documented registers exist on R-Car V3H (R8A77980) SoC. Add the corresponding device tree bindings. Signed-off-by:

		* Renesas R-Car generation 3 PCIe PHY

		This file provides information on what the device node for the R-Car
		generation 3 PCIe PHY contains.

		Required properties:
		- compatible: "renesas,r8a77980-pcie-phy" if the device is a part of the
		R8A77980 SoC.
		- reg: offset and length of the register block.
		- clocks: clock phandle and specifier pair.
		- power-domains: power domain phandle and specifier pair.
		- resets: reset phandle and specifier pair.
		- #phy-cells: see phy-bindings.txt in the same directory, must be <0>.

		Example (R-Car V3H):

		pcie-phy@e65d0000 {
		compatible = "renesas,r8a77980-pcie-phy";
		reg = <0 0xe65d0000 0 0x8000>;
		#phy-cells = <0>;
		clocks = <&cpg CPG_MOD 319>;
		power-domains = <&sysc 32>;
		resets = <&cpg 319>;
		};
