By default A5xx GPUs use CP crash dumper to get GPU
snapshot in case of any fault.
At times it is required to disable crash dumper
in case of any abnormalities, add support to do so.

When video driver queues the flush event, it doesn't convey the
port which is flushed. Due to this userspace content has to
handle the event according to the flush status variables that it
maintains. This handling can go wrong when there are concurrent
flush commands from client. Address this by adding port detail
to flush event.

During the GDSC enable sequence, the GDS_HW_CTRL forces some
clocks to be on to trigger the handshake to unhalt the SMMU
and NOC. Once the handshake completes, the controller asserts
the PWR_ON status and disables the clocks.
If the clock driver tries enabling the SMMU ahb/axi clocks
immediately, there is a possibility that these clocks might
still not have gone through their disable sequence; especially
if the AXI/AHB rates are very low. If this happens, the clock
driver falsely assumes that the clocks are on and returns. Any
SMMU accesses/traffic at this point might lead to a failure since
the clock could turn off.

Sensor temperature read function traverses the
sensor list every time without using any lock. If the
list is undergoing mutation when it is traversed, it may
result in memory violation. For example, the new element
could have added to the list before updating the
next pointer due to out of order execution. This could result
in either NULL pointer dereference or unassigned memory access
violation. Using a lock every time when temperature
is read may mutually exclude it from list mutation, but it impacts
the performance. Sensor addition is an infrequent operation
when compared to sensor temperature read. So adding a lock
to protect against this infrequent operation will add overhead
and deter performance. Use of list_for_each_entry_safe() function
for traversing, won't help. Because this function can help
only if the traversal loop removes the current element, that
is pointed by this iteration.
Use RCU when traversing and updating the list to avoid locks.
RCU ensures list traversal safe addition or deletion happens
and doesn't block the frequent read operation. Replace the
list_for_each_entry_safe() function with rcu safe list
traversal function list_for_each_entry_rcu(), wherever it is
applicable.

New requests coming after/in parallel to shutdown are being
returned with DID_ERROR, but this causes the request to be
requeued and retried. These requests are getting pulled by
the shutdown context since the PON request is inserted at
the head of the queue and the queue is run for processing.
The queuecommand in ufs driver allows requests in the context
of shutdown as PON has to be sent to the device, but this
retried regular request also ends up getting submitted after
PON which fails and causes issues in err handling.
Fix this by not relying on the context but looking for the
target lun of the request. Allow only requests directed
towards well known device lun (where PON will be sent) and
block all other requests. Also make sure we mark the
shutdown processing first before taking the write lock so
that we can appropriately fail the regular request.

Clear the CX iPeak bit if it was set by MSS before crash.
MSS sets this bit if it was in Turbo state. In a situation
where all the votes were set (including MSS), It would have
resulted in CDSP throttling. But when MSS is in crashed state,
It cannot be cleared by MSS, So PIL needs to do this. It
would allow possible clearance of throttle state.
