[media] v4l: xilinx: Add Test Pattern Generator driver 



The TPG generates multiple static or dynamic test patterns. The driver
currently hardcodes the pattern to the moving box pattern.

Xilinx Video Test Pattern Generator (TPG)

-----------------------------------------



Required properties:



- compatible: Must contain at least one of



    "xlnx,v-tpg-5.0" (TPG version 5.0)

    "xlnx,v-tpg-6.0" (TPG version 6.0)



  TPG versions backward-compatible with previous versions should list all

  compatible versions in the newer to older order.



- reg: Physical base address and length of the registers set for the device.



- clocks: Reference to the video core clock.



- xlnx,video-format, xlnx,video-width: Video format and width, as defined in

  video.txt.



- port: Video port, using the DT bindings defined in ../video-interfaces.txt.

  The TPG has a single output port numbered 0.



Optional properties:



- xlnx,vtc: A phandle referencing the Video Timing Controller that generates

  video timings for the TPG test patterns.



- timing-gpios: Specifier for a GPIO that controls the timing mux at the TPG

  input. The GPIO active level corresponds to the selection of VTC-generated

  video timings.



The xlnx,vtc and timing-gpios properties are mandatory when the TPG is

synthesized with two ports and forbidden when synthesized with one port.



Example:



	tpg_0: tpg@40050000 {

		compatible = "xlnx,v-tpg-6.0", "xlnx,v-tpg-5.0";

		reg = <0x40050000 0x10000>;

		clocks = <&clkc 15>;



		xlnx,vtc = <&vtc_3>;

		timing-gpios = <&ps7_gpio_0 55 GPIO_ACTIVE_LOW>;



		ports {

			#address-cells = <1>;

			#size-cells = <0>;



			port@0 {

				reg = <0>;



				xlnx,video-format = <XVIP_VF_YUV_422>;

				xlnx,video-width = <8>;



				tpg_in: endpoint {

					remote-endpoint = <&adv7611_out>;

				};

			};

			port@1 {

				reg = <1>;



				xlnx,video-format = <XVIP_VF_YUV_422>;

				xlnx,video-width = <8>;



				tpg1_out: endpoint {

					remote-endpoint = <&switch_in0>;

				};

			}:

		};

	};
