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>; };
