1Sitronix ST7789V RGB panel with SPI control bus
2
3Required properties:
4 - compatible: "sitronix,st7789v"
5 - reg: Chip select of the panel on the SPI bus
6 - reset-gpios: a GPIO phandle for the reset pin
7 - power-supply: phandle of the regulator that provides the supply voltage
8
9Optional properties:
10 - backlight: phandle to the backlight used
11
12The generic bindings for the SPI slaves documented in [1] also applies
13
14The device node can contain one 'port' child node with one child
15'endpoint' node, according to the bindings defined in [2]. This
16node should describe panel's video bus.
