CLK_GET(9) Clock Framework CLK_GET(9)NAMEclk_get - lookup and obtain a reference to a clock producer.
struct clk * 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.
clk_get should not be called from within interrupt context.
