Merge branch 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next
Inki writes:
"- add dmabuf attach/detach feature
. This patch would resolve performance deterioration issue
when v4l2-based driver is using the buffer imported from gem.
- drm/exynos: use DMA_ATTR_NO_KERNEL_MAPPING attribute
. With gem allocation, kernel space mapping isn't allocated and
also physical pages aren't mapped with the kernel space.
The physical pages are mapped with kernel space though vmap
function only for console framebuffer.
- add the below two patches I missed.
drm: exynos: moved exynos drm device registration to drm driver
drm: exynos: moved exynos drm hdmi device registration to drm driver
- add IPP subsystem framework and its-based device drivers.
. This patch set includes fimc, rotator and gsc drivers to perform
image scaling, rotation and color space conversion.
- add runtime pm support to hdmi driver.
- And fixups and cleanups."
