REGULATOR_SET_OPTIMU(9)		 API reference	       REGULATOR_SET_OPTIMU(9)

NAME
       regulator_set_optimum_mode - set regulator optimum operating mode

SYNOPSIS
       int regulator_set_optimum_mode(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.

       Returns the new regulator mode or error.
