clk_get — lookup and obtain a reference to a clock producer.
struct clk *clk_get( | struct device *dev, |
const char *id); |
Returns a struct clk corresponding to the clock producer, or validIS_ERR condition containing errno. The implementation usesdev andid 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 ondev.)
Drivers must assume that the clock source is not enabled.
clk_get should not be called from within interrupt context.
