This makes more sense to me, I wasn't thinking about more complex ICs like this when I made my "resistor being part of the sensing device" argument. I can see how having a new node will probably be needed. It just seems strange to ask a resistor for its current, although it is the "device" that "knows" how much current if flowing though it.. A case I'm more familiar with, fuel gauges, we have a gauge device that has a handle to the battery it is gauging [0], we still ask the "fuel-gauge" node to get out the state of charge, not the "battery" node, the battery is not a "device" from our perspective. Thinking more about that, I like your way better, so I recant my earlier objections. Andrew [0] Documentation/devicetree/bindings/power/supply/bq27xxx.txt > It's > a current sense amplifier.
