Currently, driver is determining the amount of memory to allocate
based on the event log object indexes (first, last). The last index
can change if there is additional logging done during the coredump
phase and potentially cause an out-of-bound memory access during
buffer traversal.
This change restrict the event log object traversal to a maximum
of the output buffer size.

Add validation during crtc_atomic_check to have crtc width as
multiple of 4 when dualpipe 3d-mux is enabled and multiple of 8
when quadpipe 3d-mux is enabled. This ensures each layer mixer
is having an even width.

its own clock and cannot be read without turning on the corresponding
clocks. Trying to do so might lead to unexpected behavior. This change

During MST scenario, plugging out all the downstream monitors connected
to the MST hub would trigger a disconnect handler which would cleanup
display structure. This isn't required since MST hub is still connected
and the display cleanup would be taken care during the actual MST hub
disconnect. Also, handling the disconnect immediately on port status
notification leaves the usermode in an invalid state where it assumes
the display is still enabled and results in commit errors.

When a display is powered off, the DP driver currently clears the aux
state and forces it to OFF, expecting a subsequent hpd_low. But in MST
scenarios it is possible for individual displays to be unplugged and then
plugged back in without disconnecting the hub. In this use case, after
the unplug of last display, the aux state is in OFF, and on the
subsequent plug-in, the driver appends the ON flag, leaving both flags
to be set which is an incorrect state. This change removes this
assumption and properly sets the ON/OFF state on enable/disable
respectively.

Currently we are always initializing PLL registers whenever PLL is
configured. Re-initializing PLL registers during dynamic clock switch in
case of cphy video mode is moving the PLL to some bad state resulting in
display freeze. Avoid this by restricting initialization of PLL registers
to only while turning on the PLL.

session_lock. If another DP threads holds DP session_lock then

End section of the display post enable which is supposed
to do the cleanup before exit is also setting DP aux state
as powered on and notifying the connect as successful.
If there is a race condition between connect and disconnect
paths then the code execution would skip to the end section
since display is already disabled. In this case, the DP aux
state would be misleading. This change will set the status
and notify complete only during success case.
