REGULATOR_GET_EXCLUS(9)                   API reference                   REGULATOR_GET_EXCLUS(9)



NAME
       regulator_get_exclusive - obtain exclusive access to a regulator.

SYNOPSIS
       struct regulator * regulator_get_exclusive(struct device * dev, const char * id);

ARGUMENTS
       dev
           device for regulator “consumer”

       id
           Supply name or regulator ID.

DESCRIPTION
       Returns a struct regulator corresponding to the regulator producer, or IS_ERR condition
       containing errno. Other consumers will be unable to obtain this regulator while this
       reference is held and the use count for the regulator will be initialised to reflect the
       current state of the regulator.

       This is intended for use by consumers which cannot tolerate shared use of the regulator
       such as those which need to force the regulator off for correct operation of the hardware
       they are controlling.

       Use of supply names configured via regulator_set_device_supply is strongly encouraged. It
       is recommended that the supply name used should match the name used for the supply and/or
       the relevant device pins in the datasheet.
