-* Faraday TV Encoder TVE200
-
-Required properties:
-
-- compatible: must be one of:
-	"faraday,tve200"
-	"cortina,gemini-tvc", "faraday,tve200"
-
-- reg: base address and size of the control registers block
-
-- interrupts: contains an interrupt specifier for the interrupt
-	line from the TVE200
-
-- clock-names: should contain "PCLK" for the clock line clocking the
-	silicon and "TVE" for the 27MHz clock to the video driver
-
-- clocks: contains phandle and clock specifier pairs for the entries
-	in the clock-names property. See
-	Documentation/devicetree/bindings/clock/clock-bindings.txt
-
-Optional properties:
-
-- resets: contains the reset line phandle for the block
-
-Required sub-nodes:
-
-- port: describes LCD panel signals, following the common binding
-	for video transmitter interfaces; see
-	Documentation/devicetree/bindings/media/video-interfaces.txt
-	This port should have the properties:
-	reg = <0>;
-	It should have one endpoint connected to a remote endpoint where
-	the display is connected.
-
-Example:
-
-display-controller@...00000 {
-	#address-cells = <1>;
-	#size-cells = <0>;
-	compatible = "faraday,tve200";
-	reg = <0x6a000000 0x1000>;
-	interrupts = <13 IRQ_TYPE_EDGE_RISING>;
-	resets = <&syscon GEMINI_RESET_TVC>;
-	clocks = <&syscon GEMINI_CLK_GATE_TVC>,
-		 <&syscon GEMINI_CLK_TVC>;
-	clock-names = "PCLK", "TVE";
-
-	port@0 {
-		reg = <0>;
-		display_out: endpoint {
-			remote-endpoint = <&panel_in>;
-		};
-	};
-};
