Hello all, I am currently working on a driver for a part similar to the AFE4300. I was hoping to get some information on the recommended way to handle a mux such as the one in the AFE4300 BCM front-end (page 13 of http://www.ti.com/lit/ds/symlink/afe4300.pdf has a good image). The top several pins are outputs that can be routed to the OP-AMP, but only one at a time, because of this I'm not sure if they should be exposed as output channels, or sysfs switches. The other issue is with the input pins, I believe the standard way to handle this is by exposing every mux setting as a separate channel, then only allowing one bit set in the scan mask, but for this part, when all differential combinations are exposed we have more than 100 channels, and the other part I'm working on makes this several times worse. Could someone point to any information, or an existing driver, that explains the preferred way to handle this?
