drm/panel: decouple connector from drm_panel

2019-12-09T21:57:26+00:00

To facilitate moving connector creation to display drivers, decouple the drm_connector from drm_panel. This patch adds a connector argument to drm_panel_get_modes(). All users of drm_panel_get_modes() already had the connector available, so updating users was trivial. With this patch drm_panel no longer keeps a reference to the drm_connector.

drm/msm: Remove unused function arguments

2019-10-07T15:25:30+00:00

drm/msm: split power control from prepare/complete_commit

2019-09-03T23:17:01+00:00

With atomic commit, ->prepare_commit() and ->complete_commit() may not be evenly balanced (although ->complete_commit() will complete each crtc that had been previously prepared). So these will no longer be a good place to enable/disable clocks needed for hw access. Signed-off-by: Rob Clark Reviewed-by: Sean Paul

drm/msm: add kms->flush_commit()

2019-09-03T23:17:01+00:00

Add ->flush_commit(crtc_mask). Currently a no-op, but kms backends should migrate writing flush registers to this hook, so we can decouple pushing updates to hardware, and flushing the updates. Once we add async commit support, the hw updates will be pushed down to the hw synchronously, but flushing the updates will be deferred until as close to vblank as possible, so that multiple updates can be combined in a single frame.

drm/msm: convert kms->complete_commit() to crtc_mask

2019-09-03T23:17:01+00:00

Prep work for async commits, in which case this will be called after we no longer have the atomic state object. This drops some wait_for_vblanks(), but those should be unnecessary, as we call this after waiting for flush to complete. Signed-off-by: Rob Clark Reviewed-by: Sean Paul

drm/msm: add kms->wait_flush()

2019-09-03T23:17:01+00:00

First step in re-working the atomic related internal API to prepare for async updates pending.. ->wait_flush() is intended to block until there is no in-progress flush. A crtc_mask is used, rather than an atomic state object, as this will later be used for async flush after the atomic state is destroyed. This replaces ->wait_for_crtc_commit_done() v2: update for review comments Signed-off-by: Rob Clark
