You should not squash all IP drivers such as clock manager, reset manager into one patch, this is not the right way to generate the patch, very hard for me to review the codes.

There are no rsu, smc and including secreg drivers in mainline yet, you have to upstream these drivers first or excluding these drivers related in this series.
You can submit separate patches for these changes once these drivers are available in mainline.
