Antonino A. Daplas 256154fbc3 [PATCH] fbdev: statically link the framebuffer notification functions
The backlight and lcd subsystems can be notified by the framebuffer layer
of blanking events.  However, these subsystems, as a whole, can function
independently from the framebuffer layer.  But in order to enable to the
lcd and backlight subsystems, the framebuffer has to be compiled also,
effectively sucking in a huge amount of unneeded code.

To prevent dependency problems, separate out the framebuffer notification
mechanism from the framebuffer layer and permanently link it to the kernel.

help
Enable this to be able to choose the drivers for controlling the
backlight and the LCD panel on some platforms, for example on PDAs.
config BACKLIGHT_CLASS_DEVICE

depends on BACKLIGHT_LCD_SUPPORT
default m
help
This framework adds support for low-level control of the LCD
backlight. This includes support for brightness and power.
To have support for your specific LCD panel you will have to
select the proper drivers which depend on this option.

help
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.

If you have a Sharp Zaurus SL-C7xx, SL-Cxx00 or SL-6000x say y to enable the
backlight driver.

If you have a Sharp Zaurus SL-5500 (Collie) or SL-5600 (Poodle) say y to
enable the LCD/backlight driver.

If you have a HP Jornada 680, say y to enable the
backlight driver.
