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

	#size-cells = <0>;

	<...>
