PM_SUSPEND API adds extra pm_runtime refcount and calls
the device driver for pm_suspend. At this point display
device may not be in power collapse state. This patch
makes sure that crtc_commit thread is idle and triggers
power collapse also.

Clients of local tone mapping engine need to know when hardware block
was turned off, to enable mutually exclusively display features.
Change adds support for ltm off event notification via custom event
interface of drm.

Switch to watchdog vsync whenever panel jitter is
identified during frame-transfer on command mode display.
This would allow the HW to finish processing the frame
with watchdog vsync source. Switch back to default vsync
source after the frame-transfer is complete. This would
help in the MDP hang issues in panels that generate TEs
with thresholds greater than the projected jitter.

This change moves the panel null check to the beginning of the function
so panel can be used throughout the function. This change also replaces
looping through display ctrls with proper display_for_each_ctrl.

During the validation of inline-rotator downscale ratio,
in the plane atomic_check phase, the client_type is
derived from the crtc->state. This leads to wrong
client_type as in check phase, it has to be derived
from the new crtc state. Fix it to derive from
new crtc, which would in turn be used to get the
correct inline-rotator downscale ratio.

In continuous splash use cases, the display is enabled in
the boot-loader. During display kernel probe, to enable clocks,
the rate is calculated by reading the hardware registers before
the corresponding software rate is set. At times when these rates
are nearly equal, the call for set rate never happens. This can
cause abnormal behavior. In this change during hand-off we don't
recalculate the clock rate to ensure the software programs the clock
registers accordingly.

already disabled.

Ensure that the driver is handling DSC and FEC
enablement properly. FEC can now be independently
enabled without DSC. FEC configuration is also
now performed after link training in order to
avoid link training failures as per the DP spec.
Consequently, DSC can now be left on during
compliance testing. For DSC use-cases, ensure
that the minimum supported bpp is set to 24, as
required by the DSC spec.
