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.
