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
Contact: linux-iio@vger.kernel.org
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.
