Kernel-4.18.0-80.el8_xlnx,v-tpg

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>;
            };
        };
    };
};
