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