I think we should not have adc_op_clk but rather have a property like vf610 has fsl,adck-max-frequency. Even better, would be the ability to change it with /sys/bus/iio/devices/iio:deviceX/sampling_frequency -- Alexandre Belloni, Free Electrons Embedded Linux, Kernel and Android engineering http://free-electrons.com
