[PATCH v2 9/9] iio: ABI: add DAC sysfs synchronous_mode parameter

From: Angelo Dureghello
Date: Thu Sep 05 2024 - 11:21:37 EST


From: Angelo Dureghello <adureghello@xxxxxxxxxxxx>

Some DACs as ad3552r need a synchronous mode setting, adding
this parameter for ad3552r and for future use on other DACs,
if needed.

multiple predefined symbols. Each symbol corresponds to a different

of the symbol. Writing an integer value N will select out_voltageY_rawN.

+ Arm or disarm a wait-for-synchronization flag. Arming this flag
+ means the DAC will wait for a synchronizatiopn signal on a
+ specific internal or external wired connection. I.e., there are
+ cases where multiple DACs IP are built in the same chip or fpga
+ design, and they need to start the data stream synchronized.
