Driver for the Silicon Motion SM501 multifunction device framebuffer subsystem. This driver supports both the CRT and LCD panel heads, with some simple acceleration for the cursor plotting and support for screen panning. There is no current support for bitblt/drawing engines, which should be added at a later date. This has been tested on a number of configurations, including PCI and generic-bus, on PPC, ARM and SH4 [akpm@linux-foundation.org: fix warnings] Signed-off-by: NBen Dooks <ben-linux@fluff.org> Signed-off-by: NVincent Sanders <vince@arm.linux.org.u.> Acked-by: NJames Simmons <jsimmons@infradead.org> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

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.

The backlight core listens for blanking events and triggers a backlight_update_status call so these extra calls are not needed and can be removed. Signed-off-by: NRichard Purdie <rpurdie@rpsys.net>

Remove uneeded update_status call from chipsfb.c since the backlight core now receives software blanking notifications too. Signed-off-by: NRichard Purdie <rpurdie@rpsys.net>
-
由 Richard Purdie 提交于
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.

Convert internal semaphore to a mutex Signed-off-by: NRichard Purdie <rpurdie@rpsys.net>
-
由 Richard Purdie 提交于
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: NRichard Purdie <rpurdie@rpsys.net>

由 Tim Schmielau 提交于
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).

fb_videomode_to_var(): reset the virtual screen parameters when converting from an fb_videomode to an fb_var_screeninfo. Without this the old virtual screen parameters are kept. Hence you cannot switch to a video mode with a lower resolution on frame buffer devices that don't support virtual screens and panning, as values are not supposed to be rounded down when they don't fit. I also reordered the assignments to match the order of the individual members.
