drm/exynos/fimc: fix runtime pm support

2015-08-11T08:21:35+00:00

Once pm_runtime_set_active() gets called, the kernel assumes that given
device has already enabled runtime pm and will call pm_runtime_suspend()
without matching pm_runtime_resume(). In case of DRM FIMC IPP driver,
this will result in calling clk_disable() without respective call to
clk_enable(). This patch removes call to pm_runtime_set_active() to
ensure that pm_runtime_suspend/resume calls will match.

drm/exynos: gsc: fix wrong bitwise operation for swap detection

2015-08-11T08:21:34+00:00

The bits for rotation are not used as exclusively. So GSC_IN_ROT_270 can
not be used for swap detection. The definition of it is same with
GSC_IN_ROT_MASK. It is enough to check GSC_IN_ROT_90 bit is set or not to
check whether width / height size swapping is needed.

2015-06-22T11:05:02+00:00

This patch make the driver to use an array for clock access. The number
of clocks are different from the existing MIPI DSI driver and Exynos5433
MIPI DSI driver. So this patch is needed before adding support for
Exynos5433 MIPI DSI driver.
