    Subject[PATCH v7 4/4] arm64: dts: ti: k3-j784s4-evm: Add support for TPS6594 PMIC
    Date
    From: Jerome Neanne <jneanne@baylibre.com>

    This patch adds support for TPS6593 PMIC on wkup I2C0 bus.
    This device provides regulators (bucks and LDOs), but also
    GPIOs, a RTC, a watchdog, an ESM (Error Signal Monitor)
    which monitors the SoC error output signal, and a PFSM
    (Pre-configurable Finite State Machine) which manages the
    operational modes of the PMIC.
