'1' means that the 21 pllY is locked. 22 23What: /sys/bus/iio/devices/iio:deviceX/sync_dividers 24KernelVersion: 3.4.0 25Contact: linux-iio@vger.kernel.org 26Description: 27 Writing '1' triggers the clock distribution synchronization 28 functionality. All dividers are reset and the channels start 29 with their predefined phase offsets (out_altvoltageY_phase). 30 Writing this file has the effect as driving the external 31 /SYNC pin low.
