arm64: dts: ti: k3-j784s4-evm: Add support for TPS6594 PMIC
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.
