drm/mediatek: Handle component type MTK_DISP_OVL_2L correctly

2020-02-25T05:02:22Z

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. Fixes: b17bdd0d7a73 ("drm/mediatek: add component OVL_2L0") Signed-off-by: Phong LE Signed-off-by: CK Hu

drm/mediatek: Make sure previous message done or be aborted before send

2020-02-18T08:14:38Z

Mediatek CMDQ driver removed atomic parameter and implementation related to atomic. DRM driver need to make sure previous message done or be aborted before we send next message. If previous message is still waiting for event, it means the setting hasn't been updated into display hardware register, we can abort the message and send next message to update the newest setting into display hardware. If previous message already started, we have to wait it until transmission has been completed. So we flush mbox client before we send new message to controller driver.

drm/mediatek: Move gce event property to mutex device node

2020-02-18T07:54:39Z

According mtk hardware design, stream_done0 and stream_done1 are generated by mutex, so we move gce event property to mutex device mode. Signed-off-by: Bibby Hsieh Signed-off-by: CK Hu

drm/mediatek: Add fb swap in async_update

drm/mediatek: Add plane check in async_check function

2020-02-18T07:41:50Z

MTK do rotation checking and transferring in layer check function, but we do not check that in atomic_check, so add back in atomic_check function. Fixes: 920fffcc8912 ("drm/mediatek: update cursors by using async atomic update") Signed-off-by: Bibby Hsieh Signed-off-by: CK Hu

drm/mediatek: Ensure the cursor plane is on top of other overlays

2020-02-11T01:14:47Z

Currently the cursor is placed on the first overlay plane, which means it will be at the bottom of the stack when the hw does the compositing with anything other than primary plane. Since mtk doesn't support plane zpos, change the cursor location to the top-most plane. Signed-off-by: Sean Paul Signed-off-by: CK Hu

drm/mediatek: Find the cursor plane instead of hard coding it

2020-02-11T01:14:47Z

The cursor and primary planes were hard coded. Now search for them for passing to drm_crtc_init_with_planes Signed-off-by: Evan Benn Reviewed-by: Sean Paul Signed-off-by: CK Hu
