clk_get_sys - get a clock based upon the device name
struct clk * clk_get_sys(const char * dev_id, const char * con_id);
Returns a struct clk corresponding to the clock producer, or valid IS_ERR condition containing errno. The implementation uses dev_id and 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.
