Sitronix ST7789V RGB panel with SPI control bus



Required properties:

  - compatible: "sitronix,st7789v"

  - reg: Chip select of the panel on the SPI bus

  - reset-gpios: a GPIO phandle for the reset pin

  - power-supply: phandle of the regulator that provides the supply voltage



Optional properties:

  - backlight: phandle to the backlight used



The generic bindings for the SPI slaves documented in [1] also applies



The device node can contain one 'port' child node with one child

'endpoint' node, according to the bindings defined in [2]. This

node should describe panel's video bus.

Example:



panel@0 {

	compatible = "sitronix,st7789v";

	reg = <0>;

	reset-gpios = <&pio 6 11 GPIO_ACTIVE_LOW>;

	backlight = <&pwm_bl>;

	spi-max-frequency = <100000>;

	spi-cpol;

	spi-cpha;



	port {

		panel_input: endpoint {

			remote-endpoint = <&tcon0_out_panel>;

		};

	};

};
