    1 Current Sense Amplifier
    2 =======================
    3 
    4 When an io-channel measures the output voltage from a current sense
    5 amplifier, the interesting measurement is almost always the current
    6 through the sense resistor, not the voltage output. This binding
    7 describes such a current sense circuit.
    8 
    9 Required properties:
   10 - compatible : "current-sense-amplifier"
   11 - io-channels : Channel node of a voltage io-channel.
   12 - sense-resistor-micro-ohms : The sense resistance in microohms.
   13 
   14 Optional properties:
   15 - sense-gain-mult: Amplifier gain multiplier. The default is <1>.
   16 - sense-gain-div: Amplifier gain divider. The default is <1>.
   17 
   18 Example:
   19 
   20 sysi {
   21         compatible = "current-sense-amplifier";
   22         io-channels = <&tiadc 0>;
   23 
   24         sense-resistor-micro-ohms = <20000>;
   25         sense-gain-mul = <50>;
   26 };
