devm_clk_get — lookup and obtain a managed reference to a clock producer.


struct clk * devm_clk_get (struct device * dev,
 const char * id);


struct device * dev

device for clock consumer

const char * id

clock consumer ID


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.
