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.
