+OpenCores VGA/LCD controller
+
+Required properties:
+- compatible: "opencores,ocdrm"
+- reg: Physical base address and length of the controller's registers.
+- clocks: Must contain an entry for the pixelclock generator.
+  See ../clocks/clock-bindings.txt for details.
+
+Required sub-nodes:
+- port: the connection to a DRM bridge.  The connection is modelled
+  using the OF graph bindings specified in
+  Documentation/devicetree/bindings/graph.txt.
+
+Example:
+
+ocdrm at 43c10000 {
+	compatible = "opencores,ocfb-drm";
+	reg = <0x43c10000 0x10000>;
+	clocks = <&pix_clock>;
+	ports {
+		port at 0 {
+			rgb_out: endpoint {
+				remote-endpoint = <&bridge_in>;
+			};
+		};
+	};
+};
