+Freescale MMA8452Q, MMA8453Q, MMA8652FC or MMA8653FC triaxial accelerometer
+
+Required properties:
+
+  - compatible: should be "fsl,mma8653", "fsl,mma8652", "fsl,mma8453" or
+    "fsl,mma8452" respectively.
+  - reg: the I2C address of the chip
+
+Optional properties:
+
+  - interrupt-parent: should be the phandle for the interrupt controller
+  - interrupts: interrupt mapping for GPIO IRQ
+
+Example:
+
+	mma8653fc@1d {
+		compatible = "fsl,mma8653";
+		reg = <0x1d>;
+		interrupt-parent = <&gpio1>;
+		interrupts = <5 0>;
+	};
