This PFSM controls the operational modes of the PMIC: - STANDBY and LP_STANDBY, - ACTIVE state, - MCU_ONLY state, - RETENTION state, with or without DDR and/or GPIO retention. Depending on the current operational mode, some voltage domains remain energized while others can be off. This PFSM is also used to trigger a firmware update, and provides R/W access to device registers. See Documentation/misc-devices/tps6594-pfsm.rst for more information.
