* [PATCH] nvidiafb backlight: Fix implicit declaration in nv_backlightDave Jones2007-03-06
| | | | | | | | | | | drivers/video/nvidia/nv_backlight.c: In function 'nvidia_bl_init': drivers/video/nvidia/nv_backlight.c:103: error: implicit declaration of function 'pmac_has_backlight_type' Signed-off-by: Dave Jones <davej@redhat.com> Signed-off-by: Antonino Daplas <adaplas@gmail.com> Cc: James Simmons <jsimmons@infradead.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* backlight: Allow enable/disable of fb backlights, fixing regressionsRichard Purdie2007-03-05
| | | | | | | | | Enabling the backlight by default appears to cause problems for many users. This patch disables backlight controls unless explicitly enabled by users via a module parameter. Since PMAC users are known to work, default to enabled in that case. Signed-off-by: Richard Purdie <rpurdie@rpsys.net>
* backlight: Fix nvidia backlight initial brightnessRichard Purdie2007-03-05
| | | | | | | Fix a mix up when the nvidia driver was converted resulting in the backlight having an incorrect initial brightness. Signed-off-by: Richard Purdie <rpurdie@rpsys.net>
* backlight: Separate backlight properties from backlight ops pointersRichard Purdie2007-02-20
| | | | | | | | | 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 <rpurdie@rpsys.net>
* backlight: Clean up pmac_backlight handlingRichard Purdie2007-02-20
| | | | | | | Move the setting/unsetting of pmac_backlight into the backlight core instead of doing it in each driver. Signed-off-by: Richard Purdie <rpurdie@rpsys.net>
* backlight: Rework backlight/fb interaction simplifying, lotsRichard Purdie2007-02-20
| | | | | | | | | | | | | | | | | fb_info->bl_mutex is badly thought out and the backlight class doesn't need it if the framebuffer/backlight register/unregister order is consistent, particularly after the backlight locking fixes. Fix the drivers to use the order: backlight_device_register() register_framebuffer() unregister_framebuffer() backlight_device_unregister() and turn bl_mutex into a lock for the bl_curve data only.

* backlight: Remove uneeded nvidia set_power callsRichard Purdie2007-02-20
| | | | | | | | nvidia_bl_set_power isn't needed since the backlight class handles this by receiving fb events itself and calling update_status so remove it. Signed-off-by: Richard Purdie <rpurdie@rpsys.net>
* backlight: Fix external uses of backlight internal semaphoreRichard Purdie2007-02-20
| | | | | | | | | | | | | | | | | | 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 <rpurdie@rpsys.net>
* backlight: Remove unneeded owner fieldRichard Purdie2007-02-20
| | | | | | | | | | | | Remove uneeded owner field from backlight_properties structure. Nothing uses it and it is unlikely that it will ever be used. The backlight class uses other means to ensure that nothing references unloaded code. Based on a patch from Dmitry Torokhov <dtor@insightbb.com> Signed-off-by: Richard Purdie <rpurdie@rpsys.net>
* [PATCH] remove many unneeded #includes of sched.hTim Schmielau2007-02-14
| | | | | | | | | | | | | | | | | | | | | | | | After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since we now use the generic backlight infrastructure, I think we need to call rivafb_bl_init before calling register_framebuffer since otherwise rivafb_bl_init might race with the framebuffer layer already opening the device and setting up the video mode. In this case we might end up with a not yet fully intialized backlight (info->bl_dev still NULL) when calling riva_bl_set_power via rivafb_set_par/rivafb_load_video_mode and the kernel dies without any further notice during boot. This fixes booting current git on a PB 6,1. In this case radeonfb/atyfb would be affected too - I can fix that too but don't have any hardware to test this on. Cc: "Antonino A.
