# devm\_clk\_get(9)

lookup and obtain a managed reference to a clock producer.

## NAME

devm\_clk\_get - lookup and obtain a managed reference to a clock producer.

## SYNOPSIS

**struct clk \* devm\_clk\_get(struct device \*** *dev***, const char \*** *id***);**

## ARGUMENTS

*dev*

device for clock “consumer”

*id*

clock consumer ID

## DESCRIPTION

Returns a struct clk corresponding to the clock producer, or valid **IS\_ERR** condition containing errno. The implementation uses *dev* and *id* to determine the clock consumer, and thereby the clock producer. (IOW, *id* may be identical strings, but clk\_get may return different clock producers depending on *dev*.)

Drivers must assume that the clock source is not enabled.

devm\_clk\_get should not be called from within interrupt context.

The clock will automatically be freed when the device is unbound from the bus.
