Boe Himax8279d 1200x1920 TFT LCD panel
Required properties:
- compatible: should be "boe,himax8279d8p" and one of: "boe,himax8279d10p"
- reg: DSI virtual channel of the peripheral
- enable-gpios: panel enable gpio
- pp33-gpios: a GPIO phandle for the 3.3v pin that provides the supply voltage
- pp18-gpios: a GPIO phandle for the 1.8v pin that provides the supply voltage
Optional properties:
- backlight: phandle of the backlight device attached to the panel
Example:
&mipi_dsi {
panel {
compatible = "boe,himax8279d8p", "boe,himax8279d10p";
reg = <0>;
backlight = <&backlight>;
enable-gpios = <&gpio 45 GPIO_ACTIVE_HIGH>;
pp33-gpios = <&gpio 35 GPIO_ACTIVE_HIGH>;
pp18-gpios = <&gpio 36 GPIO_ACTIVE_HIGH>;
};
};
