+ Identify the primary PMIC on SPMI bus.
+ A multi-PMIC synchronization scheme is implemented in the PMIC device
+ to synchronize the power state changes with other PMIC devices. This is
+ accomplished through a SPMI bus: the primary PMIC is the controller
+ device on the SPMI bus, and the secondary PMICs are the target devices
+ on the SPMI bus.
