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.
