Each type of regulator 10 * supports a subset of the possible modes. 11 * 12 * %RPMH_REGULATOR_MODE_RET: Retention mode in which only an extremely small 13 * load current is allowed. This mode is supported 14 * by LDO and SMPS type regulators. 15 * %RPMH_REGULATOR_MODE_LPM: Low power mode in which a small load current is 16 * allowed. This mode corresponds to PFM for SMPS 17 * and BOB type regulators. This mode is supported 18 * by LDO, HFSMPS, BOB, and PMIC4 FTSMPS type 19 * regulators. 20 * %RPMH_REGULATOR_MODE_AUTO: Auto mode in which the regulator hardware 21 * automatically switches between LPM and HPM based 22 * upon the real-time load current. This mode is 23 * supported by HFSMPS, BOB, and PMIC4 FTSMPS type 24 * regulators. 25 * %RPMH_REGULATOR_MODE_HPM: High power mode in which the full rated current 26 * of the regulator is allowed. This mode 27 * corresponds to PWM for SMPS and BOB type 28 * regulators. This mode is supported by all types 29 * of regulators. 30 */ 31#define RPMH_REGULATOR_MODE_RET 0 32#define RPMH_REGULATOR_MODE_LPM 1 33#define RPMH_REGULATOR_MODE_AUTO 2 34#define RPMH_REGULATOR_MODE_HPM 3 35 36#endif
