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>;
