The current SDE driver logic during MDP hang cases is to send a capture
event to user-mode if recovery custom event is registered. Otherwise, it
will enforce a device panic for debugging purpose. This might have a race
condition during the display tear-down sequence as user-mode unregisters
the recovery event when the last frame is in progress. If the last frame
causes any MDP hang, it will result in a device reset. Support only the
event registration to avoid this case, since HW recovery is not expected
to be changed dynamically.

In connector atomic check, seamless vrr cannot be

This change moves qsync validation from connector to encoder

This change adds support for delaying kickoff in case of ESD error.
This delay is required to handle a race condition between esd
workqueue and display thread.
When ESD workqueue detects the esd and while handling the failure
notification if the new updates arrive on display thread, there
is a possibility that ESD workqueue will keep on waiting on pp_done.
This could happen if display thread keeps on incrementing the kickoff_cnt
before workqueue can check the condition. With this change the kickoff is
delayed, allowing the workqueue to get scheduled and avoiding the race
condition.

Commit Ifa100424733 ("disp: msm: sde: delay
encoder disable for clone mode") delays the CWB
encoder disable but it is also skipping the CWB
disable flush. That can cause the underrun on dp
display if it uses the same 3d_merge HW block. This
change reverts the portion of original code and
only delays the last cwb frame done wait. It still
keep the last CWB frame done wait as it is if crtc
is also moving to inactive state.

ESD recovery schedules KICKOFF event on event_thread,
switches the vsync source to wd_timer and waits for
pending frame. This work is triggered from workthread
and it must be finished before panel dead event
notification to avoid race condition with power off
sequence. This change also cancels the delayed work
after encoder is disabled.

Currently, SDE relies on DSI to set a flag for POMS however
if a power ON modeset comes with a different mode than
previously configured, DSI is unable to detect the mode change
and does not set the flag nor perform the mode switch itself.
DSI should always align the panel mode to match the timing node
that is selected regardless of prior configurations.
SDE encoder can detect if POMS is required for the INTF block
without the flag from DSI by comparing the currently configured
INTF mode with the panel mode that is being set. The POMS flag
from DSI is still needed for any active panel mode change so
that the post-modeset cleanup operations are triggered.
