KernelVersion:    3.4.0
Contact:    linux-iio@vger.kernel.org
Description:
        Reading returns either '1' or '0'.

        '1' means that the clock in question is present.

        '0' means that the clock is missing.

What:        /sys/bus/iio/devices/iio:deviceX/pllY_locked
KernelVersion:    3.4.0

Description:
        Reading returns either '1' or '0'. '1' means that the
        pllY is locked.

What:        /sys/bus/iio/devices/iio:deviceX/sync_dividers
KernelVersion:    3.4.0
Contact:    linux-iio@vger.kernel.org
Description:
        Writing '1' triggers the clock distribution synchronization
        functionality. All dividers are reset and the channels start
        with their predefined phase offsets (out_altvoltageY_phase).
        Writing this file has the effect as driving the external
        /SYNC pin low.
