Damien Lespiau 663750141e drm/i915/skl: Add the additional graphics stolen sizes
Skylake introduces new stolen memory sizes starting at 0xf0 (4MB) and
growing by 4MB increments from there.

v2: Rebase on top of the early-quirk changes from Ville.

v3: Rebase on top of the PCI_IDS/IDS macro rename

Damien Lespiau 7f88e3af20 drm/i915/skl: Program the DDI buffer translation tables

Damien Lespiau 70d21f0e91 drm/i915/skl: Implement the new update_plane() for primary planes
Skylake makes primary planes the same as sprite planes and call the
result "universal planes".

This commit emulates a primary plane with plane 0, taking the
opportunity to redefine primary and sprite registers to be identical now
that the underlying hardware is. It also makes sense as plenty of fields
have changed.

v2: Rebase on top of the vma code.

v3: Follow upstream evolution:
- Drop return values.
- Remove pipe checks since redudant and BUG instead.
- Remove tiling checks and BUG instead.
- Drop commented out DISP_MODIFY usage.

v4: s/plane/primary_plane/

v5: Misc fixes:
- Fix the fields we need to clear up
- Disable trickle feed
- Correctly use PLANE_OFFSET for the panning

v6: (Jesse)
Use pipe src size when programming plane size. This makes cloned configs
work correctly w/o the use of a panel fitter.

v7: Rebase on top of Ville's rmw elimination series

v8: Remove clearing the trickle feed bit now that we don't do a RMW (Rodrigo,
    Damien)
    Add a comment about the stride unit (Rodrigo)

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

But not all callers do which is incorrect as far as I can tell.

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_plane_init() / drm_crtc_init() with

Additionally the patch leaves cleanup of crtcs to core,
this way planes and crtcs are cleaned in correct order.

Inki Dae 832316c704 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
  set by drm_gem_mmap
- do not include <linux/anon_inodes.h>, which isn't needed anymore.
