+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>;
+};
