  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.
  28
  29   Touchscreen bingings can be found in these files:
  30     - input/touchscreen/goodix.yaml
