-Current Sense Shunt
-===================
-
-When an io-channel measures the voltage over a current sense shunt,
-the interesting measurement is almost always the current through the
-shunt, not the voltage over it. This binding describes such a current
-sense circuit.
-
-Required properties:
-- compatible : "current-sense-shunt"
-- io-channels : Channel node of a voltage io-channel.
-- shunt-resistor-micro-ohms : The shunt resistance in microohms.
-
-Example:
-The system current is measured by measuring the voltage over a
-3.3 ohms shunt resistor.
-
-sysi {
-	compatible = "current-sense-shunt";
-	io-channels = <&tiadc 0>;
-
-	/* Divide the voltage by 3300000/1000000 (or 3.3) for the current. */
-	shunt-resistor-micro-ohms = <3300000>;
