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
|
|
select the proper drivers which depend on this option.

This provides a backlight control internal to the Atmel LCDC
|
|
driver. If the LCD "contrast control" on your board is wired
|
|
so it controls the backlight brightness, select this option to
|
|
export this as a PWM-based backlight control.
|
|
|
|
If in doubt, it's safe to enable this option; it doesn't kick
|
|
in unless the board's description says it's wired that way.
