+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.
+
+The properties bellow belong to the Synopsys DesignWare HDMI RX Decoder node.
+
+- compatible: Required property. Shall be "snps,dw-hdmi-rx".
+
+- reg: Required property. Memory mapped base address and length of the DWC
+HDMI RX registers.
+
+- interrupts: Required property. Reference to the DWC HDMI RX interrupt and
+HDMI 5V sense interrupt.
+
+- clocks: Required property. Phandle to the config clock block.
+
+- clock-names: Required property. Shall be "cfg".
+
+- edid-phandle: Optional proerty. phandle to the EDID handler block; if this
+property is not specified it is assumed that EDID is handled by device
+described by parent node of the HDMI RX node. You should not specify this
+property if your HDMI RX controller does not have CEC.
+
+- #address-cells: Required property. Shall be 1.
+
+- #size-cells: Required property. Shall be 0.
+
+You also have to create a subnode for the PHY device. PHY node properties are
+as follows.
+
+- compatible: Required property. Shall be "snps,dw-hdmi-phy-e405".
+
+- reg: Required property. Shall be JTAG address of the PHY.
+
+- clocks: Required property. Phandle for cfg clock.
+
+- clock-names: Required property. Shall be "cfg".
+
+A sample binding is now provided. The compatible string is for a SoC which has
+has a Synopsys DesignWare HDMI RX decoder inside.
+
+Example:
+
+dw_hdmi_soc: dw-hdmi-soc@0 {
+ compatible = "...";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges;
+
+ hdmi-rx@0 {
+ compatible = "snps,dw-hdmi-rx";
+ reg = <0x0 0x10000>;
+ interrupts = <1 2>;
+ edid-phandle = <&dw_hdmi_soc>;
+
+ clocks = <&dw_hdmi_refclk>;
+ clock-names = "cfg";
+
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ hdmi-phy@fc {
+ compatible = "snps,dw-hdmi-phy-e405";
+ reg = <0xfc>;
+
+ clocks = <&dw_hdmi_refclk>;
+ clock-names = "cfg";
+ };
+ };
+};
