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. |
