CLK_GET(9) Clock Framework CLK_GET(9)
NAME clk_get - lookup and obtain a reference to a clock producer.
SYNOPSIS struct clk * clk_get(struct device * dev, const char * id);
ARGUMENTS dev device for clock consumer
id clock comsumer 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.
clk_get should not be called from within interrupt context.
