+Synopsys DesignWare HDMI RX Decoder
+===================================
+
+This document defines device tree properties for the Synopsys DesignWare HDMI
+RX Decoder (DWC HDMI RX). It doesn't constitute a device tree binding
+specification by itself but is meant to be referenced by platform-specific
+device tree bindings.
+
+When referenced from platform device tree bindings the properties defined in
+this document are defined as follows.
+
+- reg: Memory mapped base address and length of the DWC HDMI RX registers.
+
+- interrupts: Reference to the DWC HDMI RX interrupt and 5v sense interrupt.
+
+- snps,hdmi-phy-jtag-addr: JTAG address of the phy to be used.
+
+- snps,hdmi-phy-version: Version of the phy to be used.
+
+- snps,hdmi-phy-cfg-clk: Value of the cfg clk that is delivered to phy.
+
+- snps,hdmi-phy-driver: *Exact* name of the phy driver to be used.
+
+- snps,hdmi-ctl-cfg-clk: Value of the cfg clk that is delivered to the
+controller.
+
+A sample binding is now provided. The compatible string is for a wrapper driver
+which then instantiates the Synopsys Designware HDMI RX decoder driver.
+
+Example:
+
+dw_hdmi_wrapper: dw-hdmi-wrapper@0 {
+	compatible = "snps,dw-hdmi-rx-wrapper";
+	reg = <0x0 0x10000>; /* controller regbank */
+	interrupts = <1 3>; /* controller interrupt + 5v sense interrupt */
+	snps,hdmi-phy-driver = "dw-hdmi-phy-e405";
+	snps,hdmi-phy-version = <405>;
+	snps,hdmi-phy-cfg-clk = <25>; /* MHz */
+	snps,hdmi-ctl-cfg-clk = <25>; /* MHz */
+	snps,hdmi-phy-jtag-addr = /bits/ 8 <0xfc>;
+};
