It is assumed that the algorithm 8e31166f0SMichael Hennerich that is used to compute the various dividers, is able to 9e31166f0SMichael Hennerich generate proper values for multiples of channel spacing. 10e31166f0SMichael Hennerich 11e31166f0SMichael HennerichWhat: /sys/bus/iio/devices/iio:deviceX/out_altvoltageY_refin_frequency 12e31166f0SMichael HennerichKernelVersion: 3.4.0 13e31166f0SMichael HennerichContact: linux-iio@vger.kernel.org 14e31166f0SMichael HennerichDescription: 15e31166f0SMichael Hennerich Sets channel Y REFin frequency in Hz. In some clock chained 16e31166f0SMichael Hennerich applications, the reference frequency used by the PLL may 17e31166f0SMichael Hennerich change during runtime. This attribute allows the user to 18e31166f0SMichael Hennerich adjust the reference frequency accordingly. 19e31166f0SMichael Hennerich The value written has no effect until out_altvoltageY_frequency 20e31166f0SMichael Hennerich is updated. Consider to use out_altvoltageY_powerdown to power 21*69078517SPeter Meerwald down the PLL and its RFOut buffers during REFin changes. 22
