+Analog Devices ADXL372 3-Axis, +/-(200g) Digital Accelerometer
+
+http://www.analog.com/media/en/technical-documentation/data-sheets/adxl372.pdf
+
+Required properties:
+ - compatible : should be "adi,adxl372"
+ - reg: SPI chip select number for the device
+ - spi-max-frequency: Max SPI frequency to use
+
+Optional properties:
+ - interrupt-parent : phandle to the parent interrupt controller as documented
+   in Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
+ - interrupts: interrupt mapping for IRQ as documented in
+   Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
+
+Example:
+
+	accelerometer@0 {
+		compatible = "adi,adxl372";
+		reg = <0>;
+		spi-max-frequency = <1000000>;
+		interrupt-parent = <&gpio>;
+		interrupts = <25 IRQ_TYPE_EDGE_FALLING>;
