drm: add generic zpos property
version 8: - move drm_blend.o from drm-y to drm_kms_helper-y to avoid EXPORT_SYMBOL(drm_atomic_helper_normalize_zpos) - remove dead function declarations in drm_crtc.h version 7: - remove useless EXPORT_SYMBOL() - better z-order wording in Documentation version 6: - add zpos in gpu documentation file - merge Ville patch about zpos initial value and API improvement. I have split Ville patch between zpos core and drivers version 5: - remove zpos range check and comeback to 0 to N-1 normalization algorithm version 4: - make sure that normalized zpos value is stay in the defined property range and warn user if not This patch adds support for generic plane's zpos property property with well-defined semantics: - added zpos properties to plane and plane state structures - added helpers for normalizing zpos properties of given set of planes - well defined semantics: planes are sorted by zpos values and then plane id value if zpos equals Normalized zpos values are calculated automatically when generic muttable zpos property has been initialized. Drivers can simply use plane_state->normalized_zpos in their atomic_check and/or plane_update callbacks without any additional calls to DRM core. Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Compare to Marek's original patch zpos property is now specific to each plane and no more to the core. Normalize function take care of the range of per plane defined range before set normalized_zpos.
