/*
* These mode constants may be used to specify modes for various RPMh regulator
* device tree properties (e.g. regulator-initial-mode). Each type of regulator
* supports a subset of the possible modes.
*
* %RPMH_REGULATOR_MODE_RET: Retention mode in which only an extremely small
* load current is allowed. This mode is supported
* by LDO and SMPS type regulators.
* %RPMH_REGULATOR_MODE_LPM: Low power mode in which a small load current is
* allowed. This mode corresponds to PFM for SMPS
* and BOB type regulators. This mode is supported
* by LDO, HFSMPS, BOB, and PMIC4 FTSMPS type
* regulators.
* %RPMH_REGULATOR_MODE_AUTO: Auto mode in which the regulator hardware
* automatically switches between LPM and HPM based
* upon the real-time load current. This mode is
* supported by HFSMPS, BOB, and PMIC4 FTSMPS type
* regulators.
* %RPMH_REGULATOR_MODE_HPM: High power mode in which the full rated current
* of the regulator is allowed. This mode
* corresponds to PWM for SMPS and BOB type
* regulators. This mode is supported by all types
* of regulators.
