Semtech's SX9500 capacitive proximity button device driver
Required properties:
- compatible: must be "semtech,sx9500"
- reg: i2c address where to find the device
- interrupt-parent : should be the phandle for the interrupt controller
- interrupts : the sole interrupt generated by the device
Refer to interrupt-controller/interrupts.txt for generic
interrupt client node bindings.
Optional properties:
- reset-gpios: Reference to the GPIO connected to the device's active
low reset pin.
Example:
sx9500@28 {
compatible = "semtech,sx9500";
reg = <0x28>;
interrupt-parent = <&gpio2>;
interrupts = <16 IRQ_TYPE_LEVEL_LOW>;
reset-gpios = <&gpio2 10 GPIO_ACTIVE_LOW>;
};
