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.
