+Freescale MMA8451Q, MMA8452Q, MMA8453Q, MMA8652FC, MMA8653FC or FXLS8471Q
+triaxial accelerometer
+
+Required properties:
+
+  - compatible: should contain one of
+    * "fsl,mma8451"
+    * "fsl,mma8452"
+    * "fsl,mma8453"
+    * "fsl,mma8652"
+    * "fsl,mma8653"
+    * "fsl,fxls8471"
+
+  - reg: the I2C address of the chip
+
+Optional properties:
+
+  - interrupts: interrupt mapping for GPIO IRQ
+
+  - interrupt-names: should contain "INT1" and/or "INT2", the accelerometer's
+		     interrupt line in use.
+
+Example:
+
+	mma8453fc@1d {
+		compatible = "fsl,mma8453";
+		reg = <0x1d>;
+		interrupt-parent = <&gpio1>;
+		interrupts = <5 0>;
+		interrupt-names = "INT2";
+	};
