A pixel format is decided according to bpp and depth, or user-requested format but fimd driver considered only bpp value to decide a proper pixel format. So this patch makes a proper pixel format to be set according to drm_framebuffer's pixel_format which is set by addfb with bpp and depth, or addfb2 with user-requested format.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The exynos4 platform is only dt-based since 3.10, we should convert driver data and ids to dt-based parsing methods. The rotator driver has a limit table to get size limit of input picture. Each SoCs has slightly different limit value compared with any others. For example, exynos4210's max_size of RGB888 is 16k x 16k. But, others have 8k x 8k. Another example the exynos5250 should have multiple of 2 pixel size for its X/Y axis. Thus, we should keep different tables for each of them. This patch also includes desciptions of each nodes for the rotator and specifies a example how to bind it.

| * drm/nouveau/bios/therm: handle vbioses with duplicate entries (mostly nva5)Martin Peres2013-09-041-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some vbioses have extra useless entries after "the end" of the table. This is problematic since all of the vbios I found with this issue redefine the pwm freq divider to insane levels (52750 Hz instead of 2500), thus breaking fan management. The first solution to solve this mess would be to change the length of the table. The solution I choose was simply to avoid setting the pwm freq twice as the other redefinitions are harmless with our current parser.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Therm uses 3 ptimer alarms. Two to drive the fan and one for polling the temperature. When suspending/resuming, alarms will never be fired. As we are checking if there isn't an alarm pending before rescheduling another one, we end up never checking temperature or updating the fan speed. This commit also adds debug messages to be able to spot more easily if this case happens again in the future. Sorry for the spam if you activate the debug level though.

On 32 bit systems then size_t is 32 bits so "total" will never be higher than UINT_MAX because of integer overflows. We need cast to u64 first before doing the math. Also the addition earlier: unsigned int num_unpins = num_cmdbufs + num_relocs; That can overflow as well, but I think it's still safe because we check both "num_cmdbufs" and "num_relocs" again in this test.

| | * drm/tegra: hdmi: Make sure clock is enabled before dumping registersMikko Perttunen2013-08-271-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The debugfs register dumping function did not enable the HDMI clock. This led to a possible system hang when reading the debugfs entry while no HDMI cable was connected to the system. This patch makes sure that the clock is enabled during the read.
