clk_get_sys — get a clock based upon the device name
|const char * dev_id,|
|const char * con_id|
Returns a struct clk corresponding to the clock producer, or
IS_ERR condition containing errno. The implementation
con_id to determine the clock consumer, and
thereby the clock producer. In contrast to
clk_get this function
takes the device name instead of the device itself for identification.
Drivers must assume that the clock source is not enabled.
clk_get_sys should not be called from within interrupt context.
