Handle release fence/frame-done error signalling for
error case like esd failure, pp_done timeout, interrupt
disable on cpu, etc. It fixes the race condition for
pending_frame count update and also triggers correct
wait function for wr_ptr wait failure.

Minimum threshold time is sum of panel jitter time, prefill lines time
and buffer time of 100usec. For panels with high jitter, we can cross the
default threshold time. Update the calculation to accommodate high jitter
panels in calculating dsi clocks.

Initialization of DSI external bridge must be done within
the initialization of DSI displays. The current method
has the drm_ext_bridge_init being called outside the
loop of DSI displays, and it will fail as the display,
encoder and connector handle are not present.
This fixes the regresion caused by
commit edef6ae040 ("disp: msm: dsi: snapshot of dsi from
4.14 to 4.19").

DP debug module is run by external script for automation testing.
DP aux and debug modules operate on shared buffers. In some race
conditions, aux and debug module can go out of sync resulting in
automation failures. Lock the buffers to make sure there are no
race conditions.

Currently, for every DP hardware register read/write, there
is a string comparison to determine the execution mode. This
adds up an extra delay while powering up/down which does a
large number of register reads and writes. During stress
testing and automation, this can cause an issue resulting
in failures. Remove the unnecessary delays by using common
APIs for register reads and writes. Switch these APIs only
in case of execution mode change.

Currently the DP display's states are not able to handle
the use cases like suspend/resume. The required steps of
host initialization and ready are not properly followed
in such cases. Define proper DP display states, set and
unset at the right places to make sure dp is in proper
state in such cases.

Send the hotplug notification to the user space only when there
is a state change e.g. from connect to disconnect, or vice versa.
This ensures that there are no spurious notifications that are
sent to the user space.

request for retire/release fences during power-mode
changes. This is used as a signal for power-mode
completion by user-mode. Allow preparing/signalling
these fences during crtc enable/disable to support it.
