2007-10-16imxfb: fast read flag and nonstandard field configurablePavel Pisa
The i.MX frame-buffer read operation should be faster for all configurations then drawing each individual character again in response to scroll events. The nonstandard fields allows to configure frame-buffer special options flags for different display configurations by board specific initialization code. One of such specific options is reversed order of pixels in each individual byte. i.MX frame-buffer seems to be designed for big-endian use first. The byte order is correctly configured for little-endian ordering, but if 1, 2 or 4 bits per pixel are used, pixels ordering is incompatible to Linux generic frame-buffer drawing functions. The patch "Allow generic BitBLT functions to work with swapped pixel order in bytes" introduces required functionality into FBDEV core. The pixels ordering selection has to be enabled at compile time CONFIG_FB_CFB_REV_PIXELS_IN_BYTE and for each display configuration which requires it by flag FB_NONSTD_REV_PIX_IN_B in "nonstd" field of info structure. This patch provides way for board specific code to select this option.

2007-05-23imxfb: remove ifdefsSascha Hauer
Here are some small fixes for the imxfb framebuffer driver: - remove ifndef for MX1FS2 platform which is not present in the kernel. - REV, CLS, PS and SPL_SPR are only needed with some sharp displays. Only setup the corresponding io pins when such a display is connected.

2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau
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).

2005-11-07[PATCH] fbcon/fbdev: Move softcursor out of fbdev to fbconAntonino A. Daplas
According to Jon Smirl, filling in the field fb_cursor with soft_cursor for drivers that do not support hardware cursors is redundant. The soft_cursor function is usable by all drivers because it is just a wrapper around fb_imageblit. And because soft_cursor is an fbcon-specific hook, the file is moved to the console directory. Thus, drivers that do not support hardware cursors can leave the fb_cursor field blank. For drivers that do, they can fill up this field with their own version. The end result is a smaller code size. And if the framebuffer console is not loaded, module/kernel size is also reduced because the soft_cursor module will also not be loaded.

2005-10-28[PATCH] DRIVER MODEL: Get rid of the obsolete tri-level suspend/resume callbacksRussell King
In PM v1, all devices were called at SUSPEND_DISABLE level. Then all devices were called at SUSPEND_SAVE_STATE level, and finally SUSPEND_POWER_DOWN level. However, with PM v2, to maintain compatibility for platform devices, I arranged for the PM v2 suspend/resume callbacks to call the old PM v1 suspend/resume callbacks three times with each level in order so that existing drivers continued to work. Since this is obsolete infrastructure which is no longer necessary, we can remove it. Here's an (untested) patch to do exactly that.
