* backlight: generic_bl: use devm_backlight_device_register()Jingoo Han2013-11-131-4/+2
| | | | | | | | Use devm_backlight_device_register() to make cleanup paths simpler. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* backlight: use dev_get_platdata()Jingoo Han2013-11-131-1/+1
| | | | | | | | | | Use the wrapper function for retrieving the platform data instead of accessing dev->platform_data directly. This is a cosmetic change to make the code simpler and enhance the readability.

* backlight: generic_bl: use pr_info() instead of printk()Jingoo Han2012-05-291-2/+4
| | | | | | | | | | | | | | Use pr_info() instead of printk() to allow dynamic debugging. The pr_fmt prefix for pr_ macros is used. Also fix checkpatch warnings as below: WARNING: printk() should include KERN_ facility level [akpm@linux-foundation.org: use KBUILD_MODNAME, per Joe] Signed-off-by: Jingoo Han <jg1.han@samsung.com> Cc: Richard Purdie <rpurdie@rpsys.net> Cc: Joe Perches <joe@perches.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* backlight: convert drivers/video/backlight/* to use module_platform_driver()Axel Lin2012-01-101-12/+1
| | | | | | | | | | | | | | | | Convert the drivers in drivers/video/backlight/* to use the module_platform_driver() macro which makes the code smaller and a bit simpler.

| | | | | | | | | | | The rename of corgibl_limit_intensity is missed in commit d00ba726 ("backlight: Rename the corgi backlight driver to generic"). Let's fix it now.

* backlight: add backlight typeMatthew Garrett2011-03-221-0/+1
| | | | | | | | | | | | | | | | | | | There may be multiple ways of controlling the backlight on a given machine. Allow drivers to expose the type of interface they are providing, making it possible for userspace to make appropriate policy decisions.

* backlight: Allow properties to be passed at registrationMatthew Garrett2010-03-161-3/+5
| | | | | | | | | | Values such as max_brightness should be set before backlights are registered, but the current API doesn't allow that. Add a parameter to backlight_device_register and update drivers to ensure that they set this correctly.

* backlight: Rename the corgi backlight driver to genericRichard Purdie2009-01-081-0/+147
The corgi backlight driver is really generic code. This rename makes this a lot clearer and completes the partial rename made a while ago. Signed-off-by: Richard Purdie <rpurdie@linux.intel.com>
