+LTC4151 High Voltage I2C Current and Voltage Monitor
+
+Required properties:
+- compatible: Must be "lltc,ltc4151"
+- reg: I2C address
+
+Optional properties:
+- shunt-resistor-micro-ohms
+	Shunt resistor value in micro-Ohms
+	Defaults to <1000> if unset.
+
+Example:
+
+ltc4151@6e {
+	compatible = "lltc,ltc4151";
+	reg = <0x6e>;
+	shunt-resistor-micro-ohms = <1500>;

+Bindings for MAX6651 and MAX6650 I2C fan controllers
+
+Reference:
+[1]	https://datasheets.maximintegrated.com/en/ds/MAX6650-MAX6651.pdf
+
+Required properties:
+- compatible : One of "maxim,max6650" or "maxim,max6651"
+- reg        : I2C address, one of 0x1b, 0x1f, 0x4b, 0x48.
+
+Optional properties, default is to retain the chip's current setting:
+- maxim,fan-microvolt : The supply voltage of the fan, either 5000000 uV or
+			12000000 uV.
+- maxim,fan-prescale  : Pre-scaling value, as per datasheet [1]. Lower values
+			allow more fine-grained control of slower fans.
+			Valid: 1, 2, 4, 8, 16.
+- maxim,fan-target-rpm: Initial requested fan rotation speed. If specified, the
+			driver selects closed-loop mode and the requested speed.
+			This ensures the fan is already running before userspace
+			takes over.
+
+Example:
+	fan-max6650: max6650@1b {
+		reg = <0x1b>;
+		compatible = "maxim,max6650";
+		maxim,fan-microvolt = <12000000>;
+		maxim,fan-prescale = <4>;
+		maxim,fan-target-rpm = <1200>;
+	};
