[ARM] 4250/1: Fix locomo backlight conversion error/compile failure

2007-03-08T13:34:01+00:00

Fix locomo backlight conversion error and subsequent compile failure from commit 599a52d12629394236d785615808845823875868. Signed-off-by: RIchard Purdie Signed-off-by: Russell King

backlight: simplify corgi_bl locking

2007-02-20T09:26:54+00:00

Now update_status has locking, we can remove the mutex from corgi_bl. Signed-off-by: Richard Purdie

backlight: Separate backlight properties from backlight ops pointers

2007-02-20T09:26:53+00:00

Per device data such as brightness belongs to the indivdual device and should therefore be separate from the the backlight operation function pointers. This patch splits the two types of data and allows simplifcation of some code. Signed-off-by: Richard Purdie

backlight: Clean up pmac_backlight handling

2007-02-20T09:26:40+00:00

Move the setting/unsetting of pmac_backlight into the backlight core instead of doing it in each driver. Signed-off-by: Richard Purdie

backlight/fbcon: Add FB_EVENT_CONBLANK

2007-02-20T08:38:45+00:00

The backlight class wants notification whenever the console is blanked but doesn't get this when hardware blanking fails and software blanking is used. Changing FB_EVENT_BLANK to report both would be a behaviour change which could confuse the console layer so add a new event for software blanking and have the backlight class listen for both.

backlight: Fix Kconfig entries

2007-02-20T08:38:45+00:00

Currently its possible to build the backlight core as a module yet compile the drivers into the kernel which gives missing symbols. Fix. Signed-off-by: Richard Purdie

backlight: Convert semaphore -> mutex

Convert internal semaphore to a mutex Signed-off-by: Richard Purdie

backlight: Fix external uses of backlight internal semaphore

2007-02-20T08:38:45+00:00

backlight_device->sem has a very specific use as documented in the header file. The external users of this are using it for a different reason, to serialise access to the update_status() method. backlight users were supposed to implement their own internal serialisation of update_status() if needed but everyone is doing things differently and incorrectly. Therefore add a global mutex to take care of serialisation for everyone, once and for all. Locking for get_brightness remains optional since most users don't need it. Also update the lcd class in a similar way. Signed-off-by: Richard Purdie

backlight: Minor code cleanups for hp680_bl.c

2007-02-20T08:38:44+00:00

Since people use this code as an example, clean it up to to use platform_*_drvdata instead of a global variable. Signed-off-by: Richard Purdie
