Currently when page fault happen, iommu driver callers camera
handler with CB details and iova address which caused the page
fault. With iommu iova address cam smmu driver finds the
closest mapping address for that cb and call the
corresponding driver to find the which port caused page fault.
This has limitation has page fault address always not mapped.
New approach is get the page fault ids from iommu driver.
Based on the Pid and Mid values, get the HW id and port ids,
go through all context which has this hw id and port id and log
the data. Once context id is identified, log the acquire data and
last consumed client address details. Dump the hw register data
in the given buffer. Send the smmu page fault event through
v4l2 queue to user.

Some usecases need more than the original max depth of 20 for ICP
contexts. Accommodate these usecases by increasing the max request
depth only for ICP.

When user space detects an error or does not receive
response for a request, Lets do a reset(LDAR) is triggered.
Before LDAR, user space sends flush command to the
kernel space.
In order to debug the cause for this situation and to dump
the information, user space sends a dump command to the
kernel space before sending flush.
As a part of this command, it passes the culprit request id
and the buffer into which the information can be dumped.
Kernel space traverses across the drivers and find the culprit hw
and dumps the relevant information in the buffer.
This data is written to a file for offline processing.
This commit dumps the information for NRT devices; JPEG,
LRME, FD and ICP.
For LRME, FD, JPEG context information is dumped.
FOR ICP, fw image is dumped.

This change attempts to retry waiting atleast 1 time for
a duration of 1 second for the abort ACK from FW. Also
adds some debug messages during flush and removes mutex
usage during page fault dump.

When the userspace issues flush, ISP driver needs to ensure that
wait and active list requests are flushed and corresponding
buffer fences are signaled with error. For active and wait lists
IFE hardware is stopped immediately. Therefore IFE must also be
reset to ensure that VFE BUS FIFOs are cleared. Start IFE HW
after receiving init packet again.

Validate the context device name with node name. If device name is
not matching return the error.
