12description:
13 TPS6594 is a Power Management IC which provides regulators and others
14 features like GPIOs, RTC, watchdog, ESMs (Error Signal Monitor), and
15 PFSM (Pre-configurable Finite State Machine) managing the state of the device.
16 TPS6594 is the super-set device while TPS6593 and LP8764 are derivatives.

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