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

24 To have support for your specific LCD panel you will have to
25 select the proper drivers which depend on this option.

122 This provides a backlight control internal to the Atmel LCDC
123 driver. If the LCD "contrast control" on your board is wired
124 so it controls the backlight brightness, select this option to
125 export this as a PWM-based backlight control.

127 If in doubt, it's safe to enable this option; it doesn't kick
128 in unless the board's description says it's wired that way.
