drm/mediatek: reduce the hbp and hfp for phy timing

2019-12-17T02:23:43Z

There are some extra data transfer in dsi. ex. LPX, hs_prepare, hs_zero, hs_exit and the sof/eof of dsi packet. This signal will enlarge the line time. So the real frame on dsi bus will be lower than calc by video timing. So dsi driver reduces the hbp and hfp to keep the line time.

drm/mediatek: Fix can't get component for external display plane.

2019-12-09T01:29:05Z

The original logic is ok for primary display, but will not find out component for external display. For example, plane->index is 6 for external display, but there are only 2 layer nr in external display, and this condition will never happen: if (plane->index < (count + mtk_ddp_comp_layer_nr(comp))) Fix this by using the offset of the plane to mtk_crtc->planes as index, instead of plane->index.

drm/mediatek: Check return value of mtk_drm_ddp_comp_for_plane.

2019-12-09T01:29:05Z

The mtk_drm_ddp_comp_for_plane can return NULL, but the usage doesn't check for it. Add check for it. Fixes: d6b53f68356f ("drm/mediatek: Add helper to get component for a plane") Signed-off-by: Pi-Hsun Shih Signed-off-by: CK Hu

drm/mediatek: Support 180 degree rotation

2019-11-06T08:00:45Z

Now that we support both reflections, we can expose 180 degree rotation and rely on the simplify routine to convert that into REFLECT_X | REFLECT_Y Signed-off-by: Sean Paul Signed-off-by: CK Hu

drm/mediatek: Support reflect-x plane rotation

2019-11-06T08:00:45Z

Add support for REFLECT_X rotations. Cc: Fritz Koenig Cc: Daniele Castagna Cc: Miguel Casas Cc: Mark Yacoub Signed-off-by: Sean Paul Signed-off-by: CK Hu

drm/mediatek: Support reflect-y plane rotation

Expose the rotation property and handle REFLECT_Y rotations. Cc: Fritz Koenig Cc: Daniele Castagna Cc: Miguel Casas Cc: Mark Yacoub Signed-off-by: Sean Paul Signed-off-by: CK Hu

drm/mediatek: Plumb supported rotation values from components to plane init

2019-11-06T08:00:44Z

This patch adds the ability for components to expose supported rotations which will be exposed to userspace via a plane rotation property. No functional changes in this patch. Signed-off-by: Sean Paul Signed-off-by: CK Hu

drm/mediatek: Add plumbing for layer_check hook

2019-11-06T08:00:44Z

This allows components to implement a .layer_check callback for their layers which is called during atomic_check. Signed-off-by: Sean Paul Signed-off-by: CK Hu

drm/mediatek: Add helper to get component for a plane

2019-11-06T08:00:44Z

Instead of hard-coding which components have planes, add a helper function to walk the components and map a plane index to a component layer. Signed-off-by: Sean Paul Signed-off-by: CK Hu
