12 description: |
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 screen 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.
