This doesn't yet cover input, but the driver does get the display working when the firmware is disabled from talking to our I2C lines.

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
|
|
|
|

|
|

#address-cells = <1>;
|

#size-cells = <0>;
