This framework adds support for low-level control of LCD.
|
|
Some framebuffer devices connect to platform-specific LCD modules
|
|
in order to have a platform-specific way to control the flat panel
|
|
(contrast and applying power to the LCD (not to the backlight!)).
|
|

To have support for your specific LCD panel you will have to
