This binding covers the official 7" (800x480) Raspberry Pi touchscreen
panel.
This DSI panel contains:
- TC358762 DSI->DPI bridge
- Atmel microcontroller on I2C for power sequencing the DSI bridge and
controlling backlight
- Touchscreen controller on I2C for touch input
and this binding covers the DSI display parts but not its touch input.
Required properties:
- compatible: Must be "raspberrypi,7inch-touchscreen-panel"
- reg: Must be "45"
- port: See panel-common.txt
Example:
dsi1: dsi@7e700000 {
#address-cells = <1>;
#size-cells = <0>;
<...>
port {
dsi_out_port: endpoint {
remote-endpoint = <&panel_dsi_port>;
};
};
};
i2c_dsi: i2c {
compatible = "i2c-gpio";
#address-cells = <1>;
#size-cells = <0>;
gpios = <&gpio 28 0
&gpio 29 0>;
lcd@45 {
compatible = "raspberrypi,7inch-touchscreen-panel";
reg = <0x45>;
port {
panel_dsi_port: endpoint {
remote-endpoint = <&dsi_out_port>;
};
};
};
};
