/*
|
|
* 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.
