This change fixes the invalid memory access. It allocates
enough memory so that out of bounds access is avoided.

This change updates the checks needed before setting the flag
to enable panel switching between command and video mode.
New crtc active state remains disabled and it causes a failure
in the previous case.

This change populates values for per_pipe_bw_high
from the device tree. This value is exposed to userspace
as the bandwidth per pipe available in the no VFE
scenario.

Each mode_set call makes sure that previous frame is triggered
and triggers the esd check if there is pp_timeout. This may
lead to deadlock between crtc commit and event threads. Crtc
commit thread acquires the rc_lock and triggers the flush_thread
API on event_thread. Event thread again tries to acquire the
rc_lock to wait for frame. This can be prevented by avoiding the
pre_kickoff call from esd_failure notification if it is generated
through pp_timeout.

Reduce the log level from error to debug for invalid
master encoder in encoder restore path during idle
power-collapse. This would avoid unnecessary logging
when concurrent writeback gets enabled after a
power-collapse event, the restore happens based on
encoder_mask attached in the crtc before the actual
enable call for the cwb encoder.

Change updates dsi clock calculations for command mode

time to hal to update mdp clocks and bandwidth needed
accordingly.

Perform mst phy operations during suspend/resume

api must also be called before and after the phy
operations to allow the system to go into deep
suspend and resume in a timely manner.

the base registration, since it is considered

When trying to get the display up on my sdm845 board I noticed that
the display wouldn't probe if I had the dsi1 node marked as "disabled"
even though my board doesn't use dsi1. It looks like the msm code
adds all nodes to its list of components even if they are disabled. I
believe this doesn't work because all registered components need to
come up before we finish probing. Let's do like other DRM code and
only add available components.

The DP HDCP layer fails to wait on and clear its internal thread
upon an HDCP stop or failure. This can result in use after free
failures if a read or write over aux channel operation is already
queued.
Update the DP HDCP layer to stop and wait on kthread completion
upon HDCP failures, and clear the kthread command queue before
resuming kthread execution. Additionally, ensure the SDE HDCP
worker thread correctly starts and stops execution upon HDCP
enablement and disablement respectively.
