Jonathan, I have an out-of tree driver I am working on mainlining. The device is a sensor that gets phase and amplitude (x and y) data on multiple physical and/or time multiplexed channels. It also has up to 4 optical encoders to get physical location. The existing driver bundles x and y together with a snapshot of the encoder sums at that moment. This seems like a good fit for iio, but one item is bothering me. How is synchronization between streams usually handled with iio drivers? Timing can be important.
