That's the problem we're try to solve. Having multiple devices and try to
determine which device is which.
eg: Mutliple adc's.
For example I have the same dac chip on multiple boards that do different
things, it's difficult to id them.
so label examples could be:
label = "current_control_group1";
label = "voltage_control_group1";
Are you totally against this or is it a problem with me not being clear
with the problem and the wording of the commit message or the example?
