DEVM_CLK_GET(9) | Clock Framework | DEVM_CLK_GET(9) |
NAME¶
devm_clk_get - lookup and obtain a managed reference to a clock producer.SYNOPSIS¶
struct clk *
devm_clk_get(struct device * dev,
const char * id);
ARGUMENTS¶
devdevice for clock “consumer”
id
clock consumer 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. devm_clk_get should not be called from within interrupt context. The clock will automatically be freed when the device is unbound from the bus.COPYRIGHT¶
