so adding this change to make it work well if user wants to
increase the backlight min level of display panel.

Dummy mixers for dedicated concurrent writeback can be allocated
as valid mixers. However, they should only be allocated for DCWB
usecases. Allocating these virtual resources incorrectly can lead
to underrun on external monitors. These dummy mixers should not
be tracked as available resources and exposed to dp for
mode validation.

In the current code, vmlock is always acquired in check
phase even if there is no transition between vm's. This
might result in janks if vmlock is held concurrently by
other processes such as backlight update. This change
ensures that vmlock is held only if there is a valid
transition request between vm's in check phase.

Current logic will unnecessarily call backlight update
twice in cases where backlight level is changing. When
this happens, there is a potential delay waiting for the
first command to complete before sending the second
backlight update with the same value. This change removes
one backlight call and now only calls update if the
property is marked as dirty.

Number of DDR Channels and DRAM efficiency factor are now device tree

Handle host_ready failures and try to initialize host if not already.
Sometimes customizations for customers causes NOC error as host_ready
doesn't return early upon failure and the customer customization
tries to access aux register to reconfig upon aux failure while
reading EDID. Adding fix will make driver more robust to handle such
cases.

In concurrent display usecases, dma_fence_array signaled op
can be called early which sets SIGNALED_BIT on spec fence, but
irq_dma_fence_array_work is not scheduled yet which clears the
PENDING_ERROR in dma_fence. Add changes to treat pending_error
with signaled cases as non fatal.

DP driver, at probe time, checks for fsa probe completion by
registering a notifier callback. The fsa driver performs some
I2C operations at this time. But occasionally, it takes multiple
attempts to complete these I2C transactions,adding huge delays
to display driver probing.If this delay is long enough, then
display usermode services start before display driver probe completes
and as a result, it fails to enumerate any displays.
Since the fsa switch is needed only after an external display is hot
plugged,this change moves the fsa probe check to dp hotplug handler.

Secondary VM will do a disable commit when transferring HW
ownership back to primary. This will end up disabling the CMD
engine before releasing HW back to primary VM. Primary is
unaware that the engine has been disabled and ends up in a
bad state until it gets re-enabled.
This issue was introduced by: commit 65f3cc3 (disp: msm: dsi:
allow cmd-engine enable/disable HW op at all times).
Fix the issue by ensuring CMD engine does not get turned off
in the display disable path for trusted VM.
