0014 This DSI panel contains:
0015
0016 - TC358762 DSI->DPI bridge
0017 - Atmel microcontroller on I2C for power sequencing the DSI bridge and
0018 controlling backlight
0019 - Touchscreen controller on I2C for touch input
0020
0021 and this binding covers the DSI display parts but not its touch input.
