KernelVersion:	3.4.0
Contact:	linux-iio@vger.kernel.org
Description:
		Stores channel Y frequency resolution/channel spacing in Hz for PLL
		devices. The given value directly influences the operating mode when
		fractional-N synthesis is required, as it derives values for
		configurable modulus parameters used in the calculation of the output
		frequency. It is assumed that the algorithm used to compute the various
		dividers is able to generate proper values for multiples of the channel
		spacing.
