drm/tegra: Changes for v4.17-rc1

This fixes mmap() for fbdev devices by providing a custom implementation
based on the KMS variant. This is a fairly exotic case these days, hence
why it is not flagged for stable.

There is also support for dedicating one of the overlay planes to serve
as a hardware cursor on older Tegra that did support hardware cursors
but not RGBA formats for it.

Planes will now also export the IN_FORMATS property by supporting the
various block-linear tiling modifiers for RGBA pixel formats.

Other than that, there's a bit of cleanup of DMA API abuse, use of the
private object infrastructure for global state (rather than subclassing
atomic state objects) and an implementation of ->{begin,end}_cpu_access
callbacks for PRIME exported buffers, which allow users to perform cache
maintenance on these buffers.

* tag 'drm/tegra/for-4.17-rc1' of git://anongit.freedesktop.org/tegra/linux:
  drm/tegra: prime: Implement ->{begin,end}_cpu_access()
  drm/tegra: gem: Map pages via the DMA API
  drm/tegra: hub: Use private object for global state
  drm/tegra: fb: Properly support linear modifier
  drm/tegra: plane: Support format modifiers
  drm/tegra: dc: Dedicate overlay plane to cursor on older Tegra's
  drm/tegra: plane: Make tegra_plane_get_overlap_index() static
  drm/tegra: fb: Implement ->fb_mmap() callback
  drm/tegra: gem: Make __tegra_gem_mmap() available more widely
  drm/tegra: gem: Reshuffle declarations

I have accumulated some patches as we went through some internal testing
for mali-dp and I was waiting for the YUV2RGB patches to land in your
tree.

* 'for-upstream/mali-dp' of git://linux-arm.org/linux-ld:
  drm: mali-dp: Add YUV->RGB conversion support for video layers
  drm: mali-dp: Turn off CRTC vblank when removing module.
  drm: arm: malidp: Use drm_atomic_helper_shutdown() to disable planes on removal
  drm: arm: malidp: Don't destroy planes manually in error handlers
  drm/mali-dp: Fix malidp_atomic_commit_hw_done() for event sending.
  drm/arm/malidp: Disable pixel alpha blending for colors that do not have alpha
  drm: mali-dp: Fix bug on scaling with rotation
  drm/mali-dp: Don't enable scaling engine for planes that only rotate.
  drm: mali-dp: Uninitialized variable in malidp_se_check_scaling()
  drm/mali-dp: Align pitch size to be multiple of bus burst read size.
  drm/mali-dp: Rotated planes need a larger pitch size.

- Continued cleanup and restructuring of powerplay
- Fetch VRAM type from vbios rather than hardcoding for SOC15 asics
- Allow ttm to drop its backing store when drivers don't need it
- DC bandwidth calc updates
- Enable DC backlight control pre-DCE11 asics
- Enable DC on all supported asics
- DC Fixes for planes due to the way our hw is ordered vs what drm expects
- DC CTM/regamma fixes
- Misc cleanup and bug fixes

These callbacks allow the exporter to swap in and pin the backing
storage for buffers as well as invalidate the cache in preparation for
accessing the buffer from the CPU, and flush the cache and unpin the
backing storage when the CPU is done modifying the buffer.

When allocating pages, map them with the DMA API in order to invalidate
caches. This is the correct usage of the API and works just as well as
faking up the SG table and using the dma_sync_sg_for_device() function.

Pass the list of valid format modifiers to planes upon initialization
and implement the ->format_mod_supported() callback so that userspace
can query for the valid combinations of formats and modifiers.

Signed-off-by: Thierry Reding <treding@nvidia.com>

Turning off the sink in this case causes various issues, because
userspace expects it to stay on until it turns it off explicitly.

Instead, turn the sink off and back on when a display is connected
again. This dance seems necessary for link training to work correctly.
