Each type of regulator 1062306a36Sopenharmony_ci * supports a subset of the possible modes. 1162306a36Sopenharmony_ci * 1262306a36Sopenharmony_ci * %RPMH_REGULATOR_MODE_RET: Retention mode in which only an extremely small 1362306a36Sopenharmony_ci * load current is allowed. This mode is supported 1462306a36Sopenharmony_ci * by LDO and SMPS type regulators. 1562306a36Sopenharmony_ci * %RPMH_REGULATOR_MODE_LPM: Low power mode in which a small load current is 1662306a36Sopenharmony_ci * allowed. This mode corresponds to PFM for SMPS 1762306a36Sopenharmony_ci * and BOB type regulators. This mode is supported 1862306a36Sopenharmony_ci * by LDO, HFSMPS, BOB, and PMIC4 FTSMPS type 1962306a36Sopenharmony_ci * regulators. 2062306a36Sopenharmony_ci * %RPMH_REGULATOR_MODE_AUTO: Auto mode in which the regulator hardware 2162306a36Sopenharmony_ci * automatically switches between LPM and HPM based 2262306a36Sopenharmony_ci * upon the real-time load current. This mode is 2362306a36Sopenharmony_ci * supported by HFSMPS, BOB, and PMIC4 FTSMPS type 2462306a36Sopenharmony_ci * regulators. 2562306a36Sopenharmony_ci * %RPMH_REGULATOR_MODE_HPM: High power mode in which the full rated current 2662306a36Sopenharmony_ci * of the regulator is allowed. This mode 2762306a36Sopenharmony_ci * corresponds to PWM for SMPS and BOB type 2862306a36Sopenharmony_ci * regulators. This mode is supported by all types 2962306a36Sopenharmony_ci * of regulators. 3062306a36Sopenharmony_ci */ 3162306a36Sopenharmony_ci#define RPMH_REGULATOR_MODE_RET 0 3262306a36Sopenharmony_ci#define RPMH_REGULATOR_MODE_LPM 1 3362306a36Sopenharmony_ci#define RPMH_REGULATOR_MODE_AUTO 2 3462306a36Sopenharmony_ci#define RPMH_REGULATOR_MODE_HPM 3 3562306a36Sopenharmony_ci 3662306a36Sopenharmony_ci#endif 37
