In the current implementation, when the display is blanked, DSI phy
is turned off prior to turning off the supply to the panel. This results
in an abrupt transition on the DSI lanes from LP11 to LP00 which is in
violation of the MIPI spec, and can potentially cause panels to go to a
bad state. Fix this by requesting ULPS entry when display is blanked.

During pipe setup, if a failure happens, the pipe
is marked as invalid and an error is returned to
the caller; it is the caller responsibility to honor
the failure and avoid an overlay play in the invalid
configuration. Anyways in order to prevent
configuration problems that can lead to underruns
due a wrong sequence by the caller, add a check
to print a warning and return an error if an
overlay play with an invalid pipe is called.

If MDSS idle power collapse feature is enabled, MDSS GDSC can get
toggled when exiting idle power collapse. This may require an
explicit call to TZ to restore MDSS security configs prior to accessing
any MDSS registers, which is typically done whenever IOMMU is attached.
For panels where backlight is controlled using DCS commands, it is
possible that a backlight update could be triggered when MDSS is power
collapsed. This would result in enabling MDSS GDSC and restoring DSI
registers prior to sending the DCS commands. For such use cases, ensure
that IOMMU is attached prior to any register programming to avoid any
crashes.

For command mode panels, current code configures the HW
to transfer a frame and returns the commit context
without waiting for transfer to finish. As an example,
after kicking off frame N transfer, commit context doesn't
wait for Frame N's transfer to finish. By doing so, it
allows SW to configure/queue frame (N+1) and improves the
performance. But before frame (N+1) is kicked off, SW needs
to make sure that frame N is finished otherwise it may lead
to tearing and/or unknown behavior. This is achieved by
calling wait4pingpong routine. But this optimization has a
side effect when debugging critical issues. If for some
reason, frame N had a bad HW configuration and it had
HW hang then wait4pingpong during frame (N+1) will timeout.
This timeout will lead to HW register dumps but this
register dump is related frame (N+1) and not frame N.
This gives incorrect debug information. To overcome this
side effect, allow wait4pingpong's timing to change using
debugfs.
Setting this node to true will make the driver
to run this processing in a synchronous way,
setting it to false will return the driver to
normal asynchronous operation:
echo 1 > /<debugfs>/mdp/serialize_wait4pp -> sync
echo 0 > /<debugfs>/mdp/serialize_wait4pp -> async (default)
