Yes, it is standalone now but it would be used by this driver and another PHC driver that I will submit later.

This file provides register definitions and belongs to the MFD change I submitted before. The MFD driver will spawn 2 devices

1) ptp hardware clock device
2) This RSMU misc device

The plan is 

1) submit mfd change
2) submit misc change
3) submit phc change
