This CL covers the following implementation, 1) Power Sensor Table parsing. 2) Power Topology Table parsing. 3) Add debugfs interface to get the current power(mW), current(mA) and voltage(uV) information from PMU. 4) Power Policy Table Parsing 5) Implement PMU boardobj interface for pmgr module. 6) Over current protection.
