1 Sitronix ST7789V RGB panel with SPI control bus
2
3 Required 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
9 Optional properties:
10   - backlight: phandle to the backlight used
11
12 The generic bindings for the SPI slaves documented in [1] also applies
13
14 The device node can contain one 'port' child node with one child
15 'endpoint' node, according to the bindings defined in [2]. This
16 node should describe panel's video bus.
