    Subject[PATCH v2 2/5] arm64: dts: ti: k3-j721s2-som-p0: Add TP6594 family PMICs
    Date
    This patch adds support for TPS6594 PMIC family on wakup I2C0 bus.
    Theses devices 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.
