To compile this driver as a module, choose M here: the module will be
called atmel-pwm-bl.
-config BACKLIGHT_CORGI

+config BACKLIGHT_GENERIC
+ tristate "Generic (aka Sharp Corgi) Backlight Driver"
depends on BACKLIGHT_CLASS_DEVICE
- default n
+ default y
help
Say y to enable the generic platform backlight driver previously
known as the Corgi backlight driver. If you have a Sharp Zaurus
- SL-C7xx, SL-Cxx00 or SL-6000x say y. Most users can say n.
-
- Note: this driver is marked as deprecated, try enable SPI and
- use the new corgi_lcd driver with integrated backlight control
+ SL-C7xx, SL-Cxx00 or SL-6000x say y.
