In Linux v6.16, the 'of_node' structure was removed from the
'i2c_board_info' structure and the 'cdi-mgr' driver fails to build.
Although it is possible to detect whether the 'i2c_board_info' structure
has the 'of_node' structure using conftest, the 'cdi-mgr' driver does
not even use this. Therefore, it is simpler to fix this by using memset
and strncpy to initialize the 'i2c_board_info' structure and this also
aligns the camera 'cdi-mgr' driver with the camera 'isc-mgr' driver that
initializes the 'i2c_board_info' structure in this way.

This driver exposes EMC frequency control interface to user space via
linux devfreq framework.
Users could change EMC frequency to the frequency value from the
available frequencies of EMC clock:
$ /sys/class/devfreq/bwmgr# cat available_frequencies
665600000 2750000000 3200000000 4266000000
and update the EMC floor frequency by writing into the min_freq QoS
sysfs node:
$ /sys/class/devfreq/bwmgr# echo 4266000000 > min_freq
and update the EMC max frequency by writing into the max_rate QoS
sysfs node to cap the EMC frequency:
$ /sys/class/devfreq/bwmgr# echo 4266000000 > max_freq
This driver does not directly manage the EMC clock rate. Instead it
just delivers the min/max frequency information to BPMP, and BPMP is
still the only entity that has the full control of EMC and other
related memory clocks.

Account NvMap allocated memory into both RSS and CG tracking to make
efficient OOM kill decisions during memory pressure.
NvMap allocates memory via kernel APIs like alloc_pages, the kernel
memory is not accounted on behalf of process who requests the
allocation. Hence in case OOM, the OOM killer never kills the process
who has allocated memory via NvMap even though this process might be
holding most of the memory.
Solve this issue using following approach:
- Use __GFP_ACCOUNT and __GFP_NORETRY flag
- __GFP_NORETRY will not let the current allocation flow to go into OOM
path, so that it will never trigger OOM.
- __GFP_ACCOUNT causes the allocation to be accounted to kmemcg. So any
allocation done by NvMap will be definitely accounted to kmemcg and
cgroups can be used to define memory limits.
- Add RSS counting for the process which allocates by NvMap, so that OOM
score for that process will get updated and OOM killer can pick this
process based upon the OOM score.
- Every process that has a reference to NvMap Handle would have the
memory size accounted into its RSS. On releasing the reference to
handle, the RSS would be reduced.

Ideally we would use the 'tegra_ivc_channel_release()' function as the
release function but because the camera-diagnostic driver does not call
'tegra_ivc_channel_create()' to create the channel and does not actually
need to free any memory, simply define a new empty function that can be
called.

OpenRM maps the buffer with remap_pfn_range and then it's user VA is
passed to libnvrm_mem to create a handle out of it. NvMap uses
get_user_pages to get user pages from the VA. It fails for the buffer
mapped with remap_pfn_range. Then it fallbacks to follow_pfn or
follow_pfnmap_start functions to obtain pfn from the VA and then obtain
page pointer from it. But as get_user_pages fails, the corresponding
error prints are getting generated even when not required. Hence reduce
the log level to debug to avoid these unnecessary spews.

Problem:
- When a Downstream Port Containment (DPC) software trigger is issued, the LTR_EN bit in the Root Port (RP) is cleared as per PCIe spec.
- However, LTR_EN bit of RTL8126 endpoint (EP) which is being expected to reset is still active and sends Latency Tolerance Reports (LTR) to RP.
- This behavior violates the PCIe spec, as LTR_EN is a non-sticky bit and should be cleared automatically on reset.
- As the RP has LTR disabled but the EP still sends LTR messages, it results in Unsupported Request (UR) errors on the RP.
- These UR errors trigger AER (Advanced Error Reporting) recovery, which includes a Secondary Bus Reset (SBR).
- The SBR causes the PCIe link to go down and come back up, but the EP again starts sending LTRs, leading to a infinite error-recovery loop.
Workaround:
- As a temporary fix, disable the LTR_EN bit in the RTL8126 EP during its probe.
- This prevents the EP from sending LTR messages, thereby avoiding UR errors and breaking the loop of AER recovery.
Impact:
- Disabling LTR prevents the EP from entering the L1.2 low power state.
- However, ASPM is currently not enabled in the system, so this workaround has no impact.

In such cases, we run into SMMU faults.
To mitigate this, a buffer size of two check was introduced so even

However, the support for this in UMD is not complete.
Therefore, disable this check until UMD is able to comply with this
