| 8 | * These mode constants may be used to specify modes for various RPMh regulator |
| 9 | * device tree properties (e.g. regulator-initial-mode). 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. |
