2015-10-08gxt4500: enable panningOndrej Zary
The driver implements pan_display but the corresponding flags are not set. Add FBINFO_HWACCEL_XPAN and FBINFO_HWACCEL_YPAN to flags to allow HW accelerated panning (for fast scrolling). Signed-off-by: Ondrej Zary <linux@rainbow-software.org> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2015-10-08gxt4500: Use arch_phys_wc_* for framebufferOndrej Zary
Add arch_phys_wc_* calls to allow write-combining using MTRR. Signed-off-by: Ondrej Zary <linux@rainbow-software.org> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2015-10-08gxt4500: fix color orderOndrej Zary
The color order in truecolor modes is wrong. This does not affect console but is visible e.g. in X11 which has wrong colors. Swap blue and red colors to fix the problem.

2015-10-08gxt4500: fix 16bpp 565 modeOndrej Zary
Fix wrong colors in 16bpp 565 mode. Signed-off-by: Ondrej Zary <linux@rainbow-software.org> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2015-10-08gxt4500: enable on non-PPC architecturesOndrej Zary
These chips can be present at least on x86 too - Fire GL2 AGP has GXT6000P but this driver is currently limited to PPC. Enable it for all architectures and add chip configuration for little-endian. Tested on x86 with Fire GL2 AGP. Signed-off-by: Ondrej Zary <linux@rainbow-software.org> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2015-08-25drivers/video/fbdev/gxt4500: Use pci_ioremap_wc_bar() to map framebufferLuis R. Rodriguez
The driver doesn't use mtrr_add() or arch_phys_wc_add() but since we know the framebuffer is isolated already on an ioremap() we can take advantage of write combining for performance where possible. In this case there are a few motivations for this: a) Take advantage of PAT when available. b) Help with the goal of eventually using _PAGE_CACHE_UC over _PAGE_CACHE_UC_MINUS on x86 on ioremap_nocache() (see commit de33c442e titled "x86 PAT: fix performance drop for glx, use UC minus for ioremap(), ioremap_nocache() and pci_mmap_page_range()").

2014-04-17video: move fbdev to drivers/video/fbdevTomi Valkeinen
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.
