- ti,system-power-controller: Telling whether or not this pmic is controlling
the system power.
- ti,sleep-enable: Enable SLEEP state.
- ti,sleep-keep-therm: Keep thermal monitoring on in sleep state.
- ti,sleep-keep-ck32k: Keep the 32KHz clock output on in sleep state.
- ti,sleep-keep-hsclk: Keep high speed internal clock on in sleep state.

- regulator-settling-time-us: Settling time, in microseconds, for voltage
change if regulator have the constant time for any level voltage change.
This is useful when regulator have exponential voltage change.
- regulator-settling-time-up-us: Settling time, in microseconds, for voltage
increase if the regulator needs a constant time to settle after voltage
increases of any level. This is useful for regulators with exponential
voltage changes.
- regulator-settling-time-down-us: Settling time, in microseconds, for voltage
decrease if the regulator needs a constant time to settle after voltage
decreases of any level. This is useful for regulators with exponential
voltage changes.
- regulator-soft-start: Enable soft start so that voltage ramps slowly
- regulator-state-mem sub-root node for Suspend-to-RAM mode
: suspend to memory, the device goes to sleep, but all data stored in memory,
