drm/mediatek: Handle component type MTK_DISP_OVL_2L correctly

2020-03-12T06:18:41+00:00

commit 3d2ed431b8f39483477bc3c3a2aefbc9778ffe12 upstream. The larb device remains NULL if the type is MTK_DISP_OVL_2L. A kernel panic is raised when a crtc uses mtk_smi_larb_get or mtk_smi_larb_put.

drm/mediatek: Add gamma property according to hardware capability

[ Upstream commit 4cebc1de506fa753301266a5a23bb21bca52ad3a ] If there is no gamma function in the crtc display path, don't add gamma property for crtc Fixes: 2f3f4dda747c ("drm/mediatek: Add gamma correction.")

drm/mediatek: handle events when enabling/disabling crtc

2020-02-24T07:38:18+00:00

[ Upstream commit 411f5c1eacfebb1f6e40b653d29447cdfe7282aa ] The driver currently handles vblank events only when updating planes on an already enabled CRTC. The atomic update API however allows requesting an event when enabling or disabling a CRTC. This currently leads to event objects being leaked in the kernel and to events not being sent out. Fix it.

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

2019-12-17T02:23:43+00:00

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.

2019-12-09T01:29:05+00:00

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.

2019-12-09T01:29:05+00:00

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

2019-11-06T08:00:45+00:00

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
