drm/mediatek: plane: Use FB's format's cpp to compute x offset

2016-08-08T18:20:02+00:00

Use the framebuffer's format to compute its cpp, and use it when
calculating the address shift value.

drm/mediatek: plane: Merge mtk_plane_enable into mtk_plane_atomic_update

2016-08-08T18:20:01+00:00

The mtk_plane_enable is just called once by mtk_plane_atomic_update.
So, merge mtk_plane_enable into mtk_plane_atomic_update.

While we are here, also clean up the function a bit by using an fb local
variables.

drm/mediatek: Use drm_atomic destroy_state helpers

2016-08-08T18:20:01+00:00

Use the core destroy_state helpers to destroy core state to ensure we don't
leak if/when more fields get added later.

drm/mediatek: Remove mtk_drm_plane

2016-08-08T18:20:00+00:00

Now that mtk_drm_plane just contains its base struct drm_plane, we can
just remove it and use struct drm_plane everywhere.

drm/mediatek: plane: Remove plane zpos/index

2016-08-08T18:20:00+00:00

It is not actually useful to a mtk plane to know its zpos/index, so just
remove this field.

This let's completely remove struct mtk_drm_plane in a follow up patch.

drm/mediatek: Use drm_plane_helper_check_state()

2016-08-08T18:19:58+00:00

Replace the use of drm_plane_helper_check_update() with
drm_plane_helper_check_state() since we have a plane state.

This also eliminates the double clipping the driver was doing
in both check and commit phases). And it should fix src coordinate
addr adjustement. Previously the driver was expecting negative dst
coordinates after clipping, which is not going happen, so any clipping
induced addr adjustment simply didn't happen. Neither did the driver
respect any user configured src coordinates, so panning and such would
have been totally broken. It should be all good now.

drm: Deal with rotation in drm_plane_helper_check_update()

2016-06-17T14:41:25+00:00

drm_plane_helper_check_update() needs to account for the plane rotation
for correct clipping/scaling calculations. Do so.

There was an earlier attempt [1] to add this into
intel_check_primary_plane() but I requested that it'd be put into the
helper instead. An updated patch never materialized AFAICS, so I went
ahead and cooked one up myself.

v2: Deal with new drm_plane_helper_check_update() callers

drm: Drop plane argument from __drm_atomic_helper_plane_destroy_state

2016-05-17T06:56:55+00:00

It's unused, and really this helper should only look at the state
structure and nothing else.

v2: Fix commit message (Laurent).

v3: Rebase onto mtk driver merge.

drm/mediatek: Add DRM Driver for Mediatek SoC MT8173.

2016-05-06T15:47:35+00:00

This patch adds an initial DRM driver for the Mediatek MT8173 DISP
subsystem. It currently supports two fixed output streams from the
OVL0/OVL1 sources to the DSI0/DPI0 sinks, respectively.
