+ * 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.
