1This binding covers the official 7" (800x480) Raspberry Pi touchscreen
2panel.
3
4This DSI panel contains:
5
6- TC358762 DSI->DPI bridge
7- Atmel microcontroller on I2C for power sequencing the DSI bridge and
8 controlling backlight
9- Touchscreen controller on I2C for touch input
10
11and this binding covers the DSI display parts but not its touch input.
12
13Required properties:
14- compatible: Must be "raspberrypi,7inch-touchscreen-panel"
15- reg: Must be "45"
16- port: See panel-common.txt
