[PATCH v7 0/4] Generic zpos property

[Benjamin Gaignard]

version 7:
remove useless EXPORT_SYMBOL()
better z-order wording in Documentation
rebased code on drm-next + merge of git://linuxtv.org/media_tree.git vsp1 branch.
vsp1 branch might be merged into 4.8-rc1 so conflits between rcar-du and zpos 
patches should be avoid in this version 7.

version 6:
add zpos in Documentation/gpu/kms-properties.csv
merge Ville's patch (splitted between all the commits)
it simplify the API and fix bug. Thanks

version 5:
rebased on drm-next where Documentation/DocBook/gpu.tmpl doesn't
exist anymore.
rework sti patch because some plane functions have changed since v4

version 4:
make sure that normalized zpos value is stay in the defined property 
range and warn user if not.
Fix NULL pointer bug in rcar-du while setting zpos value.
No changes in the other drivers.

version 3:
use kmalloc_array instead of kmalloc.
Correct normalize_zpos computation (comeback to Mareck original code)

version 2:
add a zpos property into drm_plane structure to simplify code.
This allow to get/set zpos value in core and not in drivers code.
Fix various remarks.

version 1:
refactor Marek's patches to have per plane zpos property instead of only
one in core.

Benjamin Gaignard (2):
  drm: sti: use generic zpos for plane
  drm: rcar: use generic code for managing zpos plane property

Marek Szyprowski (2):
  drm: add generic zpos property
  drm/exynos: use generic code for managing zpos plane property
