DSI-attached devices could respond to more than one virtual channel number, thus their bindings are supposed to constrain the 'reg' property to match hardware. Add missing 'reg' constrain for DSI-attached display panels, based on DTS sources in Linux kernel (assume all devices take only one channel number).

description: |
|
|
This device can be used as bridge between a host controller and LCD panels.
|
|
Currently supported LCDs are:
|
|
- LCD-OLinuXino-4.3TS
|
|
- LCD-OLinuXino-5
|
|
- LCD-OLinuXino-7
|
|
- LCD-OLinuXino-10
|
|
|
|
The panel itself contains:
|
|
- AT24C16C EEPROM holding panel identification and timing requirements
|
|
- AR1021 resistive touch screen controller (optional)
|
|
- FT5x6 capacitive touch screen controller (optional)
|
|
- GT911/GT928 capacitive touch screen controller (optional)
|
|
|
|
The above chips share same I2C bus. The EEPROM is factory preprogrammed with
|
|
device information (id, serial, etc.) and timing requirements.
|
