7aae5929cb drivers:nvpps:nvpps: support use of higher PPS freq 
- support use of higher PPS freq in nvpps. The freq value
is read from primary mac interface's "nvidia,pps_op_ctrl"
field and vetted for valid values(0,1,2,4,5 & 8).
- To use higher PPS freq, nvpps needs to update K_INT and
REF_FREQ.INC value and also increase the freq of monitoring
thread.

f01227d4ea drivers: Drop inline from driver remove wrapper 
The driver remove function is a function pointer and therefore, it does
not make sense to define the function as an 'inline'. Update the
coccinelle script and drivers to remove the inline statement.

4be2dd36bb nvidia-oot: remove module * from class_create() 
Remove the module pointer from the class_create() based
on following change in core kernel

======
driver core: class: remove module * from class_create()

The module pointer in class_create() never actually did anything, and it
shouldn't have been requred to be set as a parameter even if it did
something.  So just remove it and fix up all callers of the function in
the kernel tree at the same time.
