Kernel-4.18.0-80.el8_raspberrypi,7inch-touchscreen

This binding covers the official 7” (800x480) Raspberry Pi touchscreen
panel.

This DSI panel contains:

• TC358762 DSI->DPI bridge
• Atmel microcontroller on I2C for power sequencing the DSI bridge and
  controlling backlight
• Touchscreen controller on I2C for touch input

and this binding covers the DSI display parts but not its touch input.

Required properties:

• compatible: Must be “raspberrypi,7inch-touchscreen-panel”
• reg: Must be “45”
• port: See panel-common.txt

Example:

dsi1: dsi@7e700000 {
#address-cells = <1>;
#size-cells = <0>;
<…>

port {
    dsi_out_port: endpoint {
        remote-endpoint = <&panel_dsi_port>;
    };
};

};

i2c_dsi: i2c {
compatible = “i2c-gpio”;
#address-cells = <1>;
#size-cells = <0>;
gpios = <&gpio 28 0
&gpio 29 0>;

lcd@45 {
    compatible = "raspberrypi,7inch-touchscreen-panel";
    reg = <0x45>;

    port {
        panel_dsi_port: endpoint {
            remote-endpoint = <&dsi_out_port>;
        };
    };
};

};
