    Subject[PATCH v3 4/6] arm64: dts: ti: k3-am62a7-sk: Add support for TPS6593 PMIC
    From: Julien Panis <jpanis@baylibre.com>

    This patch adds support for TPS6593 PMIC on main 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.
