Each type of regulator 10*4882a593Smuzhiyun * supports a subset of the possible modes. 11*4882a593Smuzhiyun * 12*4882a593Smuzhiyun * %RPMH_REGULATOR_MODE_RET: Retention mode in which only an extremely small 13*4882a593Smuzhiyun * load current is allowed. This mode is supported 14*4882a593Smuzhiyun * by LDO and SMPS type regulators. 15*4882a593Smuzhiyun * %RPMH_REGULATOR_MODE_LPM: Low power mode in which a small load current is 16*4882a593Smuzhiyun * allowed. This mode corresponds to PFM for SMPS 17*4882a593Smuzhiyun * and BOB type regulators. This mode is supported 18*4882a593Smuzhiyun * by LDO, HFSMPS, BOB, and PMIC4 FTSMPS type 19*4882a593Smuzhiyun * regulators. 20*4882a593Smuzhiyun * %RPMH_REGULATOR_MODE_AUTO: Auto mode in which the regulator hardware 21*4882a593Smuzhiyun * automatically switches between LPM and HPM based 22*4882a593Smuzhiyun * upon the real-time load current. This mode is 23*4882a593Smuzhiyun * supported by HFSMPS, BOB, and PMIC4 FTSMPS type 24*4882a593Smuzhiyun * regulators. 25*4882a593Smuzhiyun * %RPMH_REGULATOR_MODE_HPM: High power mode in which the full rated current 26*4882a593Smuzhiyun * of the regulator is allowed. This mode 27*4882a593Smuzhiyun * corresponds to PWM for SMPS and BOB type 28*4882a593Smuzhiyun * regulators.
