This change updates input fence to NULL in plane state

probe might get deferred several times and get stuck

after genpd init to handle such cases.

Currently, trusted VM accepts and releases the resources
on RM notifications.
In cases, where TUI fails to submit the first frame on the trusted
vm, display cannot rely on the teardown commit IOCTL to release the
resources back to primary VM.
To handle scenarios where RM notification drops, the VM's should be
able to ACCEPT/RECLAIM resources without relying on the RM.
To address above scenarios, this change moves the resource handling
calls from notification handlers to user prompt. With this change,
trusted VM will ACCEPT the resource only on the first frame commit and
primary VM can RECLAIM the resources back if the TUI use case fails
or any of the RM notifications fail to deliver.

When continuous splash is enabled, KMS populates the modes of
a connector during splash config. With TUI VM enabled, this path
will also be exercised by trusted vm for splash handoff, where for
a given display we try to use the same HW blocks configured by
the primary VM.
Since the trusted VM invokes the path under connection_mutex lock,
calling fill_modes will lead to a deadlock. So, move the connector
mode population during init for DSI displays, since the modes are
available for the connector during initialization.

During stability stress testing, there are many instances where
the panel is unreachable which results in the ESD check mechanism
failing continuously with PANEL_DEAD events. There are two possible
reasons. Either the device is bad or DSI controller is hung. As of
today, logs/xlog is flooded and info on root cause is missed in the
logs. To catch the root cause for such issues, this patch induces
forced crash when there are five consecutive ESD check failures.

ESD recovery schedules KICKOFF event on event_thread,
switches the vsync source to wd_timer and waits for
pending frame. This work is triggered from workthread
and it must be finished before panel dead event
notification to avoid race condition with power off
sequence. This change also cancels the delayed work
after encoder is disabled.

This patch addresses 2 issues with RSC; 1) internal tracking of
certain state updates, and 2) skipping certain timing updates
in CLK state that are required.
1) With primary in video mode, RSC will override the video mode
state in favor of clock mode on RSC rev3+ HW but this override
is applied after updating the client's state and checking if a
state change is required.
If RSC is already in clock state and the client provides a video
mode state update, the state change check will proceed since the
client request doesn't match the current state, but then the
requested state gets overridden so that it does match and another
switch to clock state occurs. Fix this by moving the state update
and state change check after applying the override. Also update
the event log so the state transitions are logged properly to
help identify similar issues in the future.
2) If continuous splash is still active on a secondary display
and primary gets a mode switch, the timing update is skipped
since the RSC client requests for a CLK state update. When
secondary is then used and goes idle, solver mode can get
enabled with the wrong timing.
Primary is the only encoder allowed to provide timing updates
and it votes for CLK state when splash is active on another
display or if QSync is enabled. In both cases timing updates
should be applied in case of later transitions to solver mode.
To address the issue, add a check which ensures timing updates
are applied for these corner cases.

Setting a lower load can make the regulator enter into LPM. Now the
lower load was set before the regulator disable, there's a risk here.
The regulator has been LPM, while it was not disable, if the cosumer
has a higher current needed than LPM at this time, that will lead OCP
on this regulator. The right operation for a regulator enable/disable
should be:
1. regulator_set_voltage(vreg, active_min_uV, active_max_uV) and
regulator_set_load(vreg, active_load_uA); in either order
2. regulator_enable()
3. regulator_disable()
4. regulator_set_voltage(vreg, inactive_min_uV, inactive_max_uV)
and regulator_set_load(vreg, inactive_load_uA); in either order

Currently, SDE relies on DSI to set a flag for POMS however
if a power ON modeset comes with a different mode than
previously configured, DSI is unable to detect the mode change
and does not set the flag nor perform the mode switch itself.
DSI should always align the panel mode to match the timing node
that is selected regardless of prior configurations.
SDE encoder can detect if POMS is required for the INTF block
without the flag from DSI by comparing the currently configured
INTF mode with the panel mode that is being set. The POMS flag
from DSI is still needed for any active panel mode change so
that the post-modeset cleanup operations are triggered.
