# regulator\_set\_voltage\_time\_sel(9)

get raise/fall time

## NAME

regulator\_set\_voltage\_time\_sel - get raise/fall time

## SYNOPSIS

**int regulator\_set\_voltage\_time\_sel(struct regulator\_dev \*** *rdev***, unsigned int** *old\_selector***, unsigned int** *new\_selector***);**

## ARGUMENTS

*rdev*

regulator source device

*old\_selector*

selector for starting voltage

*new\_selector*

selector for target voltage

## DESCRIPTION

Provided with the starting and target voltage selectors, this function returns time in microseconds required to rise or fall to this new voltage

Drivers providing ramp\_delay in regulation\_constraints can use this as their **set\_voltage\_time\_sel** operation.
