 * @get_phase:	Queries the hardware to get the current phase of a clock.

 *		Returned values are 0-359 degrees on success, negative

 *		error codes on failure.

 *

 * @set_phase:	Shift the phase this clock signal in degrees specified

 *		by the second argument. Valid values for degrees are

 *		0-359. Return 0 on success, otherwise -EERROR.
