- struct clk * devm_clk_get(struct device * dev, const char * id);
- device for clock "consumer"
- 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.
