2018-07-24video: fbdev: tridentfb: remove deadcode on unreachable case statementColin Ian King1-3/+0
The value of tmp being used in the switch statement has the range of just 0..3 hence the case 4 statement can never be reached and is deadcode and can be removed. Detected by CoverityScan, CID#744384 ("Logically dead code") Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com>

pci_device_id are not supposed to change at runtime. All functions working with pci_device_id provided by <linux/pci.h> work with const pci_device_id. So mark the non-const structs as const.

2015-09-30tridentfb: Add DDC supportOndrej Zary1-5/+177
Add DDC support for Trident cards. Tested on TGUI9440, TGUI9680, 3DImage 9750, Blade3D 9880 and Blade XP. Signed-off-by: Ondrej Zary <linux@rainbow-software.org> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2015-09-24tridentfb: Fix set_lwidth on TGUI9440 and CYBER9320Ondrej Zary1-2/+8
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 <linux@rainbow-software.org> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2015-09-24tridentfb: fix hang on Blade3D with CONFIG_CC_OPTIMIZE_FOR_SIZEOndrej Zary1-1/+1
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.

2014-04-17video: move fbdev to drivers/video/fbdevTomi Valkeinen1-0/+1659
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.
