   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.
