0012 description: |
0013   This device can be used as bridge between a host controller and LCD panels.
0014   Currently supported LCDs are:
0015     - LCD-OLinuXino-4.3TS
0016     - LCD-OLinuXino-5
0017     - LCD-OLinuXino-7
0018     - LCD-OLinuXino-10
0019
0020   The panel itself contains:
0021     - AT24C16C EEPROM holding panel identification and timing requirements
0022     - AR1021 resistive touch screen controller (optional)
0023     - FT5x6 capacitive touch screnn controller (optional)
0024     - GT911/GT928 capacitive touch screen controller (optional)
0025
0026   The above chips share same I2C bus. The EEPROM is factory preprogrammed with
0027   device information (id, serial, etc.) and timing requirements.
