From: Jonathan Cameron <Jonathan.Cameron@xxxxxxxxxx>
Note this includes a fix in the example where we had *-mul instead of
*-mult. The binding doc and driver agree that it should be *-mult

-Current Sense Amplifier
-=======================
-
-When an io-channel measures the output voltage from a current sense
-amplifier, the interesting measurement is almost always the current
-through the sense resistor, not the voltage output. This binding
-describes such a current sense circuit.
-
-Required properties:
-- compatible : "current-sense-amplifier"
-- io-channels : Channel node of a voltage io-channel.
-- sense-resistor-micro-ohms : The sense resistance in microohms.
-
-Optional properties:
-- sense-gain-mult: Amplifier gain multiplier. The default is <1>.
-- sense-gain-div: Amplifier gain divider. The default is <1>.
-
-Example:
-
-sysi {
- compatible = "current-sense-amplifier";
- io-channels = <&tiadc 0>;
-
- sense-resistor-micro-ohms = <20000>;
- sense-gain-mul = <50>;
-};
