+Rockchip SoC MIPI RX D-PHY
+-------------------------------------------------------------
+
+Required properties:
+- compatible: value should be one of the following
+	"rockchip,rk3288-mipi-dphy"
+	"rockchip,rk3399-mipi-dphy"
+- clocks : list of clock specifiers, corresponding to entries in
+	clock-names property;
+- clock-names: required clock name.
+- #phy-cells: Number of cells in a PHY specifier; Should be 0.
+
+MIPI RX D-PHY use registers in "general register files", it
+should be a child of the GRF.
+
+Optional properties:
+- reg: offset and length of the register set for the device.
+- rockchip,grf: MIPI TX1RX1 D-PHY not only has its own register but also
+		the GRF, so it is only necessary for MIPI TX1RX1 D-PHY.
+
+Device node example
+-------------------
+
+grf: syscon@ff770000 {
+	compatible = "rockchip,rk3399-grf", "syscon", "simple-mfd";
+
+...
+
+	dphy: mipi-dphy {
+		compatible = "rockchip,rk3399-mipi-dphy";
+		clocks = <&cru SCLK_MIPIDPHY_REF>,
+			<&cru SCLK_DPHY_RX0_CFG>,
+			<&cru PCLK_VIO_GRF>;
+		clock-names = "dphy-ref", "dphy-cfg", "grf";
+		power-domains = <&power RK3399_PD_VIO>;
+		#phy-cells = <0>;
+	};
+};
