drm/amd/display: Fix rehook MST display not light back on

2017-12-20T19:46:38+00:00

Original applied dm_restore_drm_connector_state() has got removed.
Set link status to BAD before hotplug() event could trigger
another modeset from userspace.

The fix "Fix MST daisy chain SST not light up" commit makes so it is trying
to create a stream prior to dc_sink. That makes dc_sink is not present in
create_stream_for_sink().

drm/amd/display: Do DC mode-change check after stream creation

2017-12-20T19:46:18+00:00

Do DC level mode change checks (via dc_stream_state) only when creating
a new stream, as this check is uneccessary without a new dc_stream_state
anyways. Doing so better demonstrates the intent of this mode-change
check, in comparison to guarding it with the 'enable' flag.

drm/amd/display: remove redundant null check of array 'data'

2017-12-15T22:15:09+00:00

The null check on aconnector->base.edid_blob_ptr->data is redundant
since data is an array and can never be null.  Remove it.

drm/amd/display: remove usage of legacy_cursor_update

2017-12-06T17:48:26+00:00

Currently the atomic check code uses legacy_cursor_update
to differnetiate if the cursor plane is being requested by
the user, which is not required as we shall be updating
plane only if modeset is requested/required.

Have tested cursor plane and underlay get updated seamlessly,
without any lag or frame drops.

drm/amd/display: Do not program front-end twice

2017-12-06T17:48:11+00:00

The sequence of front-end > back-end > front-end programming will
program the front-end more than once. Add a mode_changed flag, and use
it to determine whether the front-end should be programmed before, or
after back-end.
