drm_gem_prime_fd_to_handle() and drm_gem_prime_handle_to_fd() are

When BPMP BWMGR receives ICC avg_bw requests from different memory
clients, it will sum up all avg_bw values together and use it to
determine the final EMC frequency.
Transitioning to ICC peak_bw requests will cause BPMP to evaluate
the bandwidth requirements of each memory client individually,
selecting the maximum bandwidth request from among all the clients
to determine the final EMC frequency.
This modification prevents excessive memory bandwidth allocation
when multiple host1x clients collaborate for data processing.
Currently, host1x clients request the full theoretical 100% data
bandwidth, even though the system typically doesn't fully utilize
that amount during runtime.
To address the issue of insufficient memory bandwidth when multiple
host1x clients are used together, we can reduce the boost_up_threshold
value of cactmon DFS. This adjustment ensures that when actual memory
bandwidth utilization surpasses the specified boost-up bandwidth
threshold, EMC frequency will be further scaled by one step further
to alleviate the problem.

The new Tegra Prod APIs are to be used for NVIDIA Linux kernels v5.16+.
Building the MTTCAN and QUAD SPI driver currently fail for upstream
Linux v5.16 because the various version definitions are not correct.
Some definitions have greater than v5.16.0 instead of greater than OR
equal to v5.16.0. This means that the new APIs will only be used
starting with v5.16.1+ and not v5.16.0 as inteaded.
Other definitions have less than or equal to v5.16.0 instead of just
less than v5.16.0. This means that we will still use the legacy APIs for
v5.16.0.
Fix this by correcting the definition that the drivers can be built for
upstream Linux v5.16.
