Are you going to add more stuff into this source file later on?
Yes I plan to add Tegra30 and Tegra124 CIF functions in this. Anything related to CIF can be moved here.
If not, then it's too much to have a separate driver module just for a single tiny function, you should move it into the header file (make it inline).
