The SMpro co-processor on Ampere Altra processor family is to monitor and report various data included hwmon-related info, RAS errors, and other miscellaneous information. This parent SMPro MFD driver creates a single simple register map to be shared by all sub-devices and leave all the specific to be handled by the child drivers.
