It is assumed that the algorithm 862306a36Sopenharmony_ci that is used to compute the various dividers, is able to 962306a36Sopenharmony_ci generate proper values for multiples of channel spacing. 1062306a36Sopenharmony_ci 1162306a36Sopenharmony_ciWhat: /sys/bus/iio/devices/iio:deviceX/out_altvoltageY_refin_frequency 1262306a36Sopenharmony_ciKernelVersion: 3.4.0 1362306a36Sopenharmony_ciContact: linux-iio@vger.kernel.org 1462306a36Sopenharmony_ciDescription: 1562306a36Sopenharmony_ci Sets channel Y REFin frequency in Hz. In some clock chained 1662306a36Sopenharmony_ci applications, the reference frequency used by the PLL may 1762306a36Sopenharmony_ci change during runtime. This attribute allows the user to 1862306a36Sopenharmony_ci adjust the reference frequency accordingly. 1962306a36Sopenharmony_ci The value written has no effect until out_altvoltageY_frequency 2062306a36Sopenharmony_ci is updated. Consider to use out_altvoltageY_powerdown to power 2162306a36Sopenharmony_ci down the PLL and its RFOut buffers during REFin changes. 22
