drm: sti: add VID layer VIDeo plug are one of the compositor input sub-devices. VID are dedicated to video inputs like YUV plans. Like GDP, VID are part of Compositor hardware block and use sti_layer structure to provide an abstraction for Compositor calls.

drm/sti: code clean up Purpose is to simplify the STI driver: - remove layer structure - consider video subdev as part of the compositor (like mixer subdev) - remove useless STI_VID0 and STI_VID1 enum Signed-off-by: Vincent Abriou <vincent.abriou@st.com> Reviewed-by: Benjamin Gaignard <benjamin.gaignard@linaro.org>

drm/sti: atomic crtc/plane update Better fit STI hardware structure. Planes are no more responsible of updating mixer information such as z-order and status. It is now up to the CRTC atomic flush to do it. Plane actions (enable or disable) are performed atomically. Disabling of a plane is synchronize with the vsync event.

drm: sti: use late_register and early_unregister callbacks Make sti driver use register callback to move debugfs initialization out of sub-components creation. This will allow to convert driver .load() to drm_dev_alloc() and drm_dev_register(). sti_compositor bring up 2 crtc but only one debugfs init is needed so use drm_crtc_index to do it on the first one. This can't be done in sti_drv because only sti_compositor have access to the devices. It is almost the same for sti_encoder which handle multiple encoder while one only debugfs entry is needed so add a boolean to avoid multiple debugfs initialization Signed-off-by: Benjamin Gaignard <benjamin.gaignard@linaro.org> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1466514580-15194-3-git-send-email-benjamin.gaignard@linaro.org
