    Subject[PATCH v7 1/6] dt-bindings: mfd: Add TI TPS6594 PMIC
    Date
    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.

    + 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.
