drm/ttm: Clean usage of ttm_io_prot() with TTM_PL_FLAG_CACHED
Today, most callers of ttm_io_prot() check TTM_PL_FLAG_CACHED before
calling it since on some archs it will unconditionally create non-cached
mappings.
But not all callers do which is incorrect as far as I can tell.
Instead, move that check inside ttm_io_port() itself for all archs
and make powerpc use the same implementation as ia64 and arm

Merge branch 'exynos-drm-next' of git://git./linux/kernel/git/daeinki/drm-exynos into drm-next
Sorry for late. This pull request includes some enhancements
for Exynos drm, new feature supports, cleanups and fixups
like below,
- Consider low power transmission for drm mipi dsi module,
and also add non-continuous clock mode support for Exynos
mipi dsi driver.
- Add Exynos3250 SoC support.
- Enhance and clean up ipp framework and fimc driver.
- Update to use component match support and fix up
de-initialization order.
- Remove a direct mmap interface and relevant stuff specific to
Exynos drm, use drm generic mmap interface instead.
And we will remove the specific interface from userspace
library, libdrm soon.
- Use universal plane which allows to replace fake primary plane
with the real one.
- Some code cleanups and fixups.

drm/exynos: use drm generic mmap interface
This patch removes DRM_EXYNOS_GEM_MMAP ictrl feature specific
to Exynos drm and instead uses drm generic mmap.
We had used the interface specific to Exynos drm to do mmap directly,
not to use demand paging which maps each page with physical memory
at page fault handler. We don't need the specific mmap interface
because the drm generic mmap which uses vm offset manager stuff can
also do mmap directly.
This patch makes a userspace region to be mapped with whole physical
memory region allocated by userspace request when mmap system call is
requested.
Changelog v2:
- do not set VM_IO, VM_DONTEXPEND and VM_DONTDUMP. These flags were already

drm/tilcdc: panel: Fix backlight devicetree support
The current backlight support is broken; the driver expects a backlight-class
in the panel devicetree node. Fix this by implementing it properly, getting
an optional backlight from a phandle.
This shouldn't cause any backward-compatibility DT issue because the current
implementation doesn't work and is not even documented.
