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