Sometimes committed state doesn't contain any crtcs. For example,
fbdev emulation is still pushing null commits to DRM even if the
cable has been plugged out. Avoid flooding the logs in this case.

The default PWM gpio pin mode was not right for PWM backlight

Cache controller is not a sde property, add
proper parsing logic to get the compatible version
of llcc cache.
Featurise system cache support with a catalog entry as it
provides a finer control to enable/disable llcc

Use MDP scratch registers to pass drm mode index information
between the VMs. Expose the APIs which LA VM can use to set
the current mode for all active displays before handoff.
LE VM relies on this information to set the corresponding
display in correct mode during handoff.

client_pre_release/client_post_acquire hooks in vm_ops allows non-SDE
clients to register for callbacks to be invoked
- before releasing the resources from the current VM so that
the client can updates the respective sw state to indicate
the absence of HW ownership
- before the first frame push after acquiring the HW to update
reset the respective sw state to indicate the presence of
HW ownership and resume operations

When hpd disconnect is received, the dp driver sends an uevent to
usermode and waits for the usermode to tear down all external displays
before turning off the dp link. If the wait for uevent completion
times out or exits prematurely due to a race condition with the
connect path, it is possible for the dp link to be turned off
prematurely, with displays still in enabled state. On a subsequent
hpd disconnect, the driver attempts to disable the display causing
this issue since the link has been already turned off.
This change adds a check for display status after uevent handling and
before turning off dp link, to make sure the displays are always
cleaned up before the link is turned off. Any future attempts to
disable from usermode will be ignored.

When dp disconnect is triggered, as part of the teardown process, the
driver sends a notification to audio driver and waits for the audio
driver to complete before proceeding. When back to back disconnects
are triggered currently there is no check if a disconnect is already
in progress. So the driver ends up reinitializing the signal
completion that the previous disconnect thread is waiting on causing
this issue.
This change adds a check at the beginning of disconnect handling and
bail out if a disconnect is already in progress.

Commit d46cae019e ("disp: msm: sde: trigger pm_qos vote
with irq enable") moves the pm_qos vote with irq
enable/disable state. Such irq enable/disable call may be
triggered from atomic context and lead to scheduling issues
due to mutex_lock usage in pm_qos APIs. This change moves
the vote with encoder idle pc to allow lock usage with sleep.
