[v5,1/4] dt-bindings: mfd: Add TI TPS6594 PMIC
Commit Message
TPS6594 is a Power Management IC which provides regulators and others
features like GPIOs, RTC, watchdog, ESMs (Error Signal Monitor), and
PFSM (Pre-configurable Finite State Machine) managing the state of the
device.
TPS6594 is the super-set device while TPS6593 and LP8764 are derivatives.

+ 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.
