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>;
};
