tridentfb: Add DDC support

2015-09-30T07:46:55Z

Add DDC support for Trident cards. Tested on TGUI9440, TGUI9680, 3DImage 9750, Blade3D 9880 and Blade XP. Signed-off-by: Ondrej Zary Signed-off-by: Tomi Valkeinen

tridentfb: Fix set_lwidth on TGUI9440 and CYBER9320

2015-09-24T11:35:37Z

According to X.Org driver, chips older than TGUI9660 have only 1 width bit in AddColReg. Touching the 2nd one causes I2C/DDC to fail on TGUI9440. Set only 1 bit of width in AddColReg on TGUI9440 and CYBER9320. Signed-off-by: Ondrej Zary Signed-off-by: Tomi Valkeinen

tridentfb: fix hang on Blade3D with CONFIG_CC_OPTIMIZE_FOR_SIZE

2015-09-24T11:35:36Z

When the kernel is compiled with -Os (CONFIG_CC_OPTIMIZE_FOR_SIZE), tridentfb hangs the machine upon load with Blade3D cards unless acceleration is disabled. This is caused by memcpy() which copies data byte-by-byte (rep movsb) when compiled with -Os. The card does not like that - it requires 32-bit access. Use iowrite_32() instead.

video: move fbdev to drivers/video/fbdev

2014-04-17T05:10:19Z

The drivers/video directory is a mess. It contains generic video related files, directories for backlight, console, linux logo, lots of fbdev device drivers, fbdev framework files. Make some order into the chaos by creating drivers/video/fbdev directory, and move all fbdev related files there. No functionality is changed, although I guess it is possible that some subtle Makefile build order related issue could be created by this patch.
