REGULATOR_SET_LOAD(9)                     API reference                     REGULATOR_SET_LOAD(9)



NAME
       regulator_set_load - set regulator load

SYNOPSIS
       int regulator_set_load(struct regulator * regulator, int uA_load);

ARGUMENTS
       regulator
           regulator source

       uA_load
           load current

DESCRIPTION
       Notifies the regulator core of a new device load. This is then used by DRMS (if enabled by
       constraints) to set the most efficient regulator operating mode for the new regulator
       loading.

       Consumer devices notify their supply regulator of the maximum power they will require (can
       be taken from device datasheet in the power consumption tables) when they change
       operational status and hence power state. Examples of operational state changes that can
       affect power consumption are :-

       o Device is opened / closed. o Device I/O is about to begin or has just finished. o Device
       is idling in between work.

       This information is also exported via sysfs to userspace.

       DRMS will sum the total requested load on the regulator and change to the most efficient
       operating mode if platform constraints allow.

       On error a negative errno is returned.
