Merge branch 'generic-zpos-v8' of http://git.linaro.org/people/benjamin.gaignard/kernel into drm-next
Merge generic ZPOS property support, this was backed up behind some other changes I didn't have a stable branch point for. Now they are merged to Linus tree this pull is just drm patches. * 'generic-zpos-v8' of http://git.linaro.org/people/benjamin.gaignard/kernel: drm: rcar: use generic code for managing zpos plane property drm/exynos: use generic code for managing zpos plane property drm: sti: use generic zpos for plane drm: add generic zpos property
