+Synopsys DesignWare HDMI RX Decoder
+===================================
+
+This document defines device tree properties for the Synopsys DesignWare HDMI
+RX Decoder (DWC HDMI RX).
+
+The properties bellow belong to the Synopsys DesignWare HDMI RX Decoder node.
+
+Required properties:
+
+- compatible: Shall be "snps,dw-hdmi-rx".
+- reg: Memory mapped base address and length of the DWC HDMI RX registers.
+- interrupts: Reference to the DWC HDMI RX interrupt and the HDMI 5V sense
+interrupt.
+- clocks: Reference to the config clock.
+- clock-names: Shall be "cfg".
+- #address-cells: Shall be 1.
+- #size-cells: Shall be 0.
+
+Optional properties:
+
+- edid-phandle: Reference 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.
+
+You also have to create a subnode for the PHY device. PHY node properties are
+as follows.
+
+Required properties:
+
+- compatible: Shall be "snps,dw-hdmi-phy-e405".
+- reg: Shall be the JTAG address of the PHY.
+- clocks: Reference to the config clock.
+- clock-names: Shall be "cfg".
+
+Example:
+
+hdmi_rx: hdmi-rx@0 {
+ compatible = "snps,dw-hdmi-rx";
+ reg = <0x0 0x10000>;
+ interrupts = <1 2>;
+ edid-phandle = <&dw_hdmi_edid>;
+
+ 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";
+ };
+};
