13  This device can be used as bridge between a host controller and LCD panels.
14  Currently supported LCDs are:
15    - LCD-OLinuXino-4.3TS
16    - LCD-OLinuXino-5
17    - LCD-OLinuXino-7
18    - LCD-OLinuXino-10
19
20  The panel itself contains:
21    - AT24C16C EEPROM holding panel identification and timing requirements
22    - AR1021 resistive touch screen controller (optional)
23    - FT5x6 capacitive touch screnn controller (optional)
24    - GT911/GT928 capacitive touch screen controller (optional)
25
26  The above chips share same I2C bus. The EEPROM is factory preprogrammed with
27  device information (id, serial, etc.) and timing requirements.
