    Ah, that explains what it is. Sorry, use
    in_proximitiy0_sampling_frequency to provide equivalent
    control please. Might be a pain here, but this interface will just
    provide the same info as the existing
    one in a different form. Note that sampling_frequency is documented as
    a general one, but can
    be extended to individual channels.

    Actually add it to the iio-core as an element in the info_mask as I
    doubt this will be the last time
    we see this control. This will need to be a precursor patch to the
    driver obviously.

    IIO_CHAN_INFO_SAMP_FREQ and the relevant shared and separate macros need
    to go in
    iio.h + the text entry in industrialio-core.c

    If you like I can do this but it'll be quicker if you do :)
