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.
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 implements the framework for traversal
across the RT and NRT devices.

Add register information. Initial QoS settings info to program
camera static settings for chipsets having camera v170_200.
Also change the logic to get the camera and cpas versions.
Added the map table corresponding to camera and cpas versions.
For any new CPAS version support, just need to add the entries to
the map. This removes the complexity of if-else cases while
fetching the cpas hw information.

This change reduces the duration of wait for config done during
stop and flush. We perform wait for completion once for reg
dump during flush so there is no need for a long wait during
stop.

CDM driver read the user_data reg to inform CDM's clients
about the request status being served. If before clearing
the IRQ, the value of userdata register gets updated, then
CDM will not receive another INLINE_IRQ for the updated
userdata.
This change will make sure that another interrupt is fired
by clearing the IRQ first and reading the userdata later.

This change reduces the maximum attempts to apply a particular
request from three to two. After two failed attempts to apply
to ISP device, IRQs for ISP device will be overlapped from
two requests. Thereafter apply request at every alternate
frame will fail without a chance of recovery. Therefore we
must notify userspace to trigger recover on the link.

During resetting if sensor tries to apply Init setting, it fails.

This change disables overflow recovery/detection for
custom CSID. Currently for QCOM CSID we enable overflow
detection and freeze on overflow. But for custom HW the
CSID needs to be free running, custom HW will take care
of handling any backpressure from IFE pipeline/DDR.
There is no need to backpressure to CSID in case of custom
HW.
