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
