Hello,

I have an IIO adc driver that measures temperatures and voltages on the SOC.
There are other kernel modules interested in the temperature and voltage event 
information.

Would using a custom callback registration mechanism be advisable?
Is there something similar done already in IIO that can be leveraged?


Hi,

Have a look at the IIO consumer API that allows other kernel modules to 
subscribe to the output of an IIO device.
