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>;
};
};
};
