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. */ #define RPMH_REGULATOR_MODE_RET 0 #define RPMH_REGULATOR_MODE_LPM 1 #define RPMH_REGULATOR_MODE_AUTO 2 #define RPMH_REGULATOR_MODE_HPM 3 #endif
