129 * clk_get_sys - get a clock based upon the device name
130 * @dev_id: device name
131 * @con_id: connection ID
132 *
133 * Returns a struct clk corresponding to the clock producer, or
134 * valid IS_ERR() condition containing errno. The implementation
135 * uses @dev_id and @con_id to determine the clock consumer, and
136 * thereby the clock producer. In contrast to clk_get() this function
137 * takes the device name instead of the device itself for identification.
138 *
139 * Drivers must assume that the clock source is not enabled.
140 *
141 * clk_get_sys should not be called from within interrupt context.
