/* |
|
* 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. |
