This change enables ESD check after panel operating
mode switch is done.

Remove session lock for power state update to improve functionality
for fast hotplug use cases. This allows the controller and aux modules
to be updated asynchronously based on hotplug state. For example,
in disconnected state all aux transactions will be aborted.
Updates to the power state can be done without the session lock
since this path is only exercised during compliance testing.

There is an audio turn off timeout error whenever DP handles
the link state toggling requests from sink during audio
playback session. The audio hw is waiting for DMA write done
interrupts before issuing a audio session tear down. As the
DP controller is put into reset before link training, the
DMA write done is not sent by the DP controller hence causing
audio timeout errors. These changes turn off audio before the
DP controller is put into reset so that the audio session
tear down takes place within the stipulated time.

2 Frames transfer pending is possible with posted start.
One ongoing frame and another triggered frame. Current SW
waits for pp_done interrupt if pending frame count is greater
than 1. It is possible that interrupt may be missed for ongoing
frame. In that case, SW should run pp_done wait for one by one
frame instead of two frames together. It allows encoder to
check the ctl scheduler status and trigger the frame done
event on time.

Use one level lower test pattern in case the current
test pattern fails to train link. This helps with few
monitors which sometimes fail with a selected test
pattern. Instead of failing the link, try with a lower
test pattern.

Currently LUTDMA kickoff is immediately followed by CTL flush,
immaterial of the LUTDMA DONE status in command mode. If LUTDMA
kickoff happens too close to the read_ptr in auto-refresh case, it might
cause a race condition between LUTDMA & CTL flush, due to a HW issue.
Serialize LUTDMA & CTL flush by making the LUTDMA kickoff as blocking
to avoid the race condition in auto-refresh case similar to video mode.

Initialization of DSI external bridge must be done within

has the drm_ext_bridge_init being called outside the

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.
