REGULATOR_GET_OPTION(9)                   API reference                   REGULATOR_GET_OPTION(9)



NAME
       regulator_get_optional - obtain optional access to a regulator.

SYNOPSIS
       struct regulator * regulator_get_optional(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.

       This is intended for use by consumers for devices which can have some supplies unconnected
       in normal use, such as some MMC devices. It can allow the regulator core to provide stub
       supplies for other supplies requested using normal regulator_get calls without disrupting
       the operation of drivers that can handle absent supplies.

       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.
