CLK_GET_SYS(9)							  Clock Framework						    CLK_GET_SYS(9)

NAME
       clk_get_sys - get a clock based upon the device name

SYNOPSIS
       struct clk * clk_get_sys(const char * dev_id, const char * con_id);

ARGUMENTS
       dev_id
	   device name

       con_id
	   connection ID

DESCRIPTION
       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.
