+* Microchip MCP98XX temperature sensor
+
+http://ww1.microchip.com/downloads/en/DeviceDoc/25095A.pdf
+
+Required properties:
+
+  - compatible: must be "microchip,mcp98xx"
+  - reg: the I2C address of the sensor
+  - interrupt-parent: should be the phandle for the interrupt controller
+  - interrupts: the sole interrupt generated by the device
+
+  Refer to interrupt-controller/interrupts.txt for generic
+  interrupt client node bindings.
+
+Example:
+
+mcp9808@18 {
+	compatible = "microchip,mcp98xx";
+	reg = <0x18>;
+	interrupt-parent = <&gpio1>;
+	interrupts = <16 1>;
+};
