		* clk_get_sys - get a clock based upon the device name
		* @dev_id: device name
		* @con_id: connection 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.
