+Qualcomm adreno/snapdragon MDP4 display controller
+
+Description:
+
+This is the bindings documentation for the MDP4 display controller found in
+SoCs like MSM8960, APQ8064 and MSM8660.
+
+Required properties:
+- compatible:
+  * "qcom,mdp4" - mdp4
+- reg: Physical base address and length of the controller's registers.
+- interrupts: The interrupt signal from the display controller.
+- clocks: device clocks
+  See ../clocks/clock-bindings.txt for details.
+- clock-names: the following clocks are required.
+  * "core_clk"
+  * "iface_clk"
+  * "bus_clk"
+  * "lut_clk"
+  * "hdmi_clk"
+  * "tv_clk"
+- ports: contains the list of output ports from MDP. These connect to interfaces
+  that are external to the MDP hardware, such as HDMI, DSI, EDP etc (LVDS is a
+  special case since it is a part of the MDP block itself).
+
+  Each output port contains an endpoint that describes how it is connected to an
+  external interface. These are described by the standard properties documented
+  here:
+	Documentation/devicetree/bindings/graph.txt
+	Documentation/devicetree/bindings/media/video-interfaces.txt
+
+  The output port mappings are:
+	Port 0 -> LCDC/LVDS
+	Port 1 -> DSI1 Cmd/Video
+	Port 2 -> DSI2 Cmd/Video
+	Port 3 -> DTV
+
+Optional properties:
+- clock-names: the following clocks are optional:
+  * "lut_clk"
+
+Example:
+
+/ {
+	...
+
+	hdmi: hdmi@4a00000 {
+		...
+		ports {
+			...
+			port@0 {
+				reg = <0>;
+				hdmi_in: endpoint {
+					remote-endpoint = <&mdp_dtv_out>;
+				};
+			};
+			...
+		};
+		...
+	};
+
+	...
+
+	mdp: mdp@5100000 {
+		compatible = "qcom,mdp4";
+		reg = <0x05100000 0xf0000>;
+		interrupts = <GIC_SPI 75 0>;
+		clock-names =
+		    "core_clk",
+		    "iface_clk",
+		    "lut_clk",
+		    "hdmi_clk",
+		    "tv_clk";
+		clocks =
+		    <&mmcc MDP_CLK>,
+		    <&mmcc MDP_AHB_CLK>,
+		    <&mmcc MDP_AXI_CLK>,
+		    <&mmcc MDP_LUT_CLK>,
+		    <&mmcc HDMI_TV_CLK>,
+		    <&mmcc MDP_TV_CLK>;
+
+		ports {
+			#address-cells = <1>;
+			#size-cells = <0>;
+
+				port@0 {
+					reg = <0>;
+					mdp_lvds_out: endpoint {
+					};
+				};
+
+				port@1 {
+					reg = <1>;
+					mdp_dsi1_out: endpoint {
+					};
+				};
+
+				port@2 {
+					reg = <2>;
+					mdp_dsi2_out: endpoint {
+					};
+				};
+
+				port@3 {
+					reg = <3>;
+					mdp_dtv_out: endpoint {
+						remote-endpoint = <&hdmi_in>;
+					};
+				};
+		};
+	};
+};
