[GIT PULL] drm/imx: pending update handling, plane zpos property

[Philipp Zabel]

please consider merging these imx-drm updates for v5.1.
Same content as the imx-drm-next-2019-02-13 pull request, but rebased
onto v5.0-rc7, with a Tested-by: on the zpos patch, and two commit typo
fixes in commit messages.

regards
Philipp

  drm/imx: only send commit done event when all state has been applied (2019-02-22 12:17:58 +0100)

----------------------------------------------------------------
drm/imx: handle pending updates better, add plane zpos property support

- Add a mechanism to only send commit done events once all pending
  updates have been applied. This closes a small race window where
  already armed events could fire even though the double buffered
  hardware update just missed the update window.
- Add plane zpos property support to allow placing the overlay plane
  behind the primary plane.
- Allow building imx-drm on all platforms under COMPILE_TEST.
