The issue scenario is as follows:
1. User space issues CWB commit N-1, frame got picked up and wr_ptr_irq
is received.
2. Next commit N CWB disable commit is programmed waits for N-1 wb_done
irq.
3. The kickoff count is decremented on wb_done_irq of commit N-1
and wb wait_for_idle is exited.
4. wb_frame_done irq thread execution stalled before populating fences
and commit thread execution continues.
5. wb_reset disables in_clone_mode flag, the stalled wb_done_irq thread
resumes its execution and signals the release fences on primary crtc.
6. Commit N-1 frame_done irq is received and release fences is
signaled again.
Made changes to avoid the race between irq thread and commit thread
over in_clone_mode flag, by adding a lock over wb physical encoder.

When poms supported panel is booting up with video mode
rsc timers are not configured. Made changes to update rsc
timers configuration during bootup with video mode as well,
to avoid rsc stuck issues during poms switch.

In the case of DMS the dsi phy timings get updated in
dsi_display_set_mode() and the clock in pre_kickoff().
This brings a mismatch between phy timing and the clock between the
above two operations. For example, during dsi_display_enable(),
the HW is programmed with the new phy timings but the clock is still
running at the older rate. This mismatch can lead to screen flicker
or error.
Update the phy timings and clocks together during pre_kickoff().

During suspend-resume in a dual-display scenario with primary
display topology <2 2 1> and secondary display topology <1 1 1>
with 3 DSC instances, allocating DSC block 1 to the secondary
display results in DSC blocks 2 and 3 being assigned to the
primary display. However, as DSC block 2 is not a peer of DSC
block 3, it triggers an atomic check failure as a part of the RM
reservation failure. While reserving the DSC resources, prefer non
pairable DSC if the topology requests for single DSC instance. If
there are no non pairable DSCs available, then select one of the
available DSC.

In legacy POMS feature, there were separate timing nodes for
video and command mode. So, while calculating the total number
of modes, 1 extra mode is added for command mode if POMS feature
is enabled in video mode panel.
But as per the new design, this is clubbed into one timing node.
So, there is no separate mode for command mode. This change removes
the check to add 1 extra mode count otherwise it leads to null
pointer dereference while getting lm for this extra mode. Also
avoid overriding mode capability when POMS is enabled.

In POMS use case while disabling the virtual encoder, the virt
reset function sets the current master to null. concurrently, if
there is a query from the DRM client for the current vsync count,
it returns a zero value. This results in the blocking of the
drm_crtc_funcs.disable_vblank function. since the vsync count
has been relocated to the virtual encoder, remove the physical
encoder structure.

In POMS use case, the handling of the wait for vsync event
completion coincides with the concurrent
drm_crtc_funcs.enable_vblank. This concurrency causes a vsync
event complete timeout while disabling the encoder. to fix this
concurrency problem, increment the vblank refcount in encoder
disable and release the vblank refcount in encoder enable.

In CWB use case along with suspend commit, the function
drm_crtc_funcs.get_vblank_counter returns a zero vsync count
value. This causes blocking of drm_crtc_funcs.disable_vblank,
leading to a wait for vsync timeout while disabling the encoder.
hence clear a cwb encoder mask in encoder disable and set it
while performing mode set.

During PM suspend in dual display usecase, the power off commit to
turn off primary and secondary crtcs is done with only one
drm_atomic_state scheduled on primary crtc_commit thread. At the
same, touch events can happen on secondary panel, which will
run input_event_work and schedule the sde_enc->delayed_off_work
to turn off its enabled resources. There can be race between primary
crtc_commit thread which unregisters input_event, cancels
all the pending works before setting sde_enc->cur_master to NULL
and input_event_work_handler which schedules the delayed_off_work
without checking the input_event_handler state.
This change adds input handler unregister check before triggering
_sde_encoder_rc_early_wakeup.
