clk_get - lookup and obtain a reference to a clock producer.
2. SYNOPSIS ▲
struct clk * clk_get(struct device * dev , const char * id );
3. ARGUMENTS ▲
device for clock « consumer »
clock consumer ID
4. 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.
