DEVM_CLK_GET(9) Clock Framework DEVM_CLK_GET(9)NAMEdevm_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
dev
device 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.
