0001 What:           /sys/bus/iio/devices/iio:deviceX/out_altvoltageY_frequency_resolution
0002 KernelVersion:  3.4.0
0003 Contact:        linux-iio@vger.kernel.org
0004 Description:
0005                 Stores channel Y frequency resolution/channel spacing in Hz.
0006                 The value given directly influences the MODULUS used by
0007                 the fractional-N PLL. It is assumed that the algorithm
0008                 that is used to compute the various dividers, is able to
0009                 generate proper values for multiples of channel spacing.

0011 What:           /sys/bus/iio/devices/iio:deviceX/out_altvoltageY_refin_frequency
0012 KernelVersion:  3.4.0
0013 Contact:        linux-iio@vger.kernel.org
0014 Description:
0015                 Sets channel Y REFin frequency in Hz. In some clock chained
0016                 applications, the reference frequency used by the PLL may
0017                 change during runtime. This attribute allows the user to
0018                 adjust the reference frequency accordingly.
0019                 The value written has no effect until out_altvoltageY_frequency
0020                 is updated. Consider to use out_altvoltageY_powerdown to power
0021                 down the PLL and its RFOut buffers during REFin changes.
