Kionix KXSD9 Accelerometer device tree bindings



Required properties:

 - compatible: 		should be set to "kionix,kxsd9"

 - reg:			i2c slave address



Optional properties:

 - vdd-supply:		The input supply for VDD

 - iovdd-supply:	The input supply for IOVDD

 - interrupts:		The movement detection interrupt

 - mount-matrix:	See mount-matrix.txt



Example:



kxsd9@18 {

	compatible = "kionix,kxsd9";

	reg = <0x18>;

	interrupt-parent = <&foo>;

	interrupts = <57 IRQ_TYPE_EDGE_FALLING>;

	iovdd-supply = <&bar>;

	vdd-supply = <&baz>;

};
