From: Esteban Blanc <eblanc@xxxxxxxxxxxx> 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.
