+Synopsys DesignWare MIPI Rx D-PHY block details
+
+Description
+-----------
+
+The Synopsys MIPI D-PHY controller supports MIPI-DPHY in receiver mode.
+Please refer to phy-bindings.txt for more information.
+
+Required properties:
+- compatible		: Shall be "snps,dphy-rx".
+- #phy-cells		: Must be 1.
+- snps,dphy-frequency	: Output frequency of the D-PHY.
+- snps,dphy-te-len	: Size of the communication interface (8 bits->8 or 12bits->12).
+- reg			: Physical base address and size of the device memory mapped
+		 	  registers;
+
+Optional properties:
+- snps,compat-mode	: Compatibility mode control
+
+The per-board settings:
+- gpios 		: Synopsys testchip used as reference uses this to change setup
+  		  	  configurations.
+
+Example:
+
+	mipi_dphy_rx1: dphy@3040 {
+		compatible = "snps,dphy-rx";
+		#phy-cells = <1>;
+		snps,dphy-frequency = <300000>;
+		snps,dphy-te-len = <12>;
+		snps,compat-mode = <1>;
+		reg = < 0x03040 0x20
+			0x08000 0x100
+			0x09000 0x100>;
+	};
