Embedded controller return minimum and maximum frequencies, unfortunately we have no way to know the step for all available frequencies. Even if not complete, we can return a list of known values using the standard read_avail callback (IIO_CHAN_INFO_SAMP_FREQ) to provide them to userland. Now cros_ec_* sensors provides frequencies values in sysfs like this: "0 min max". 0 is always true to disable the sensor. Default frequencies are provided for earlier protocol.
