drm: move drm_mode related functions into drm_modes.c Makes more sense and gives better grouping in the DocBook function reference sections. To make this possible we need to expose two functions from drm_crtc.c though. To avoid further namespace pollution in the system wide headers create a new internal header for such drm internal symbols. I expect that longer-term we'll add tons more, but since my goal here is to polish the kerneldoc that's for another day.

drm/atomic: Hide drm.ko internal interfaces This is just a bit fallout from patch polishing and moving the get_prop logic fully into the core: - Drop EXPORT_SYMBOL and make the helpers static. - Drop kerneldoc since not used by drivers. - Move the cross-file function declarations only used by drm.ko internally to an internal header. v2: keep the gist of the comments, requested by Rob.

drm: Add callbacks for late registering Like what has been done for connectors add callbacks on encoder, crtc and plane to let driver do actions after drm device registration. Correspondingly, add callbacks called before unregister drm device. version 2: add drm_modeset_register_all() and drm_modeset_unregister_all() to centralize all calls version 3: in error case unwind registers in drm_modeset_register_all fix uninitialed return value inverse order of unregistration in drm_modeset_unregister_all version 4: move function definitions in drm_crtc_internal.h remove not needed documentation Signed-off-by: Benjamin Gaignard <benjamin.gaignard@linaro.org> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1466519829-4000-1-git-send-email-benjamin.gaignard@linaro.org

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.
