+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>;
+ };
