67ce55687b disp: msm: dp: optimize sim function handling in dp_debug
Remove edid/dpcd simulation function from dp_debug and calls to
sim bridge instead to simplify dp_debug module. Also add mst edid
support and mst hpd simulation from aux level.

Move selected mode from dp_debug module to dp_panel module to
simplify mst handling and decouple dp_debug from main dp driver.

Remove custom edid/dpcd mode from dp_panel and dp_aux module.
Remove mst connector list handling from dp_display module.

3e26909b0a disp: msm: dp: abort aux before going to dp suspend
During resume, DP uses AUX to perform various functionalities
like DPCD/EDID read or link training etc. This involves other
hardware modules as well like USB and Charger. In a situation
like continuous suspend/resume, while DP is processing resume,
suspend can trigger resulting in dependent hardware modules
to go to sleep. As AUX communication is hardware interrupt
based, this can result in unstable system.

Abort all functionalities before going to suspend to
avoid unnecessary AUX and other functionality failures.

4ca56193c5 disp: msm: dp: synchronize debug and aux common buffer handling
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.

Add a new state to indicate timeout failures in simulation mode.
This can be used by test scripts to trigger a retry of the
session.
