With MDP idle power collapse feature enabled, MDSS GDSC gets turned off
whenever there are no updates sent to the panel which results in all
hardware registers getting reset. These hardware registers need to be
restored whenever on the next udpate. Currently, this restore
functionality is only supported for command mode panels. However it is
possible that there could be additional framebuffer devices that may be
active (such as a writeback device) in conjunction with the primary
panel. In such cases, if idle power collapse happens, then these control
paths may not get correctly restored leading to unexpected behaviors.
Fix this by preventing MDP idle power-collapse when such panels are
active.

Most likely root cause of ping-pong timeouts is a pipeline hang in the
display controller. These pipeline hangs can happen due to bad frame
configuration and if this bad configuration persists every frame then
ping-pong timeouts will flood the console with warning logs and may lead
to watchdog bite. Fix this by reporting ping-pong timeout only once every
bad configuration.

In split display mode, the clocks for both the DSI controllers are
sourced out of a single PLL (typically the left controller). In the
current implementation, the clocks are independently controlled whenever
the broadcast mode is not enabled. However, it is possible that if the
clocks for right controller alone are turned on, the left controller's
phy could already be clamped, leading to that PLL not getting locked.
Fix this issue by ensuring that the clocks for the master controller
(left controller) are always turned on whenever the clocks for the right
controller (or the slave controller) are turned on.

When MDSS idle power collapse feature is enabled, MDSS GDSC can be
turned off for idle screen usecases. As a result, whenever MDSS
GDSC is turned back on, all MDSS registers need to be restored.
Current implementation restores this as part of bus bandwidth control
API which is only called whenever interface clocks are turned on.
However, the correct approach is to restore the hardware state whenever
any new register programming needs to be done. Therefore, move the
call to restore MDSS state from the bus bandwidth control function over
to the MDSS clock control function.

Currently MDP driver rejects reusing of a pipe if this reuse results
in wastage of SMPs. i.e. VIG0 pipe reused from YUV layer to RGB layer.
In this case, since RGB layer needs only plane0, plane1 SMPs are unused.
This kind of wasting leads to un-necessary GPU fall-backs for composition
when number of SMPs and number of pipes are less. For this reason driver
used to prohibit such configuration. But in high tier chip-sets, there
are enough number of SMPs and pipes are available such that these
transient wastage of SMPs can be absorbed without much impact.
