The LP873X chip is a power management IC for Portable Navigation Systems
    and Tablet Computing devices. It contains the following components:

     - Regulators.
     - Configurable General Purpose Output Signals(GPO).

PMIC interacts with the main processor through i2c. PMIC has
couple of LDOs(Linear Regulators), couple of BUCKs (Step-Down DC-DC
Converter Cores) and GPOs(General Purpose Output Signals). At this
time only the regulator functionality is made available.
