1SEMTECH SX150x GPIO expander bindings
2
3
4Required properties:
5
6- compatible: should be "semtech,sx1506q",
7			"semtech,sx1508q",
8			"semtech,sx1509q".
9
10- reg: The I2C slave address for this device.
11
12- interrupt-parent: phandle of the parent interrupt controller.
13
14- interrupts: Interrupt specifier for the controllers interrupt.
15
16- #gpio-cells: Should be 2. The first cell is the GPIO number and the
17		second cell is used to specify optional parameters:
18		bit 0: polarity (0: normal, 1: inverted)
19
20- gpio-controller: Marks the device as a GPIO controller.
21
22- interrupt-controller: Marks the device as a interrupt controller.
23
24The GPIO expander can optionally be used as an interrupt controller, in
25which case it uses the default two cell specifier as described in
26Documentation/devicetree/bindings/interrupt-controller/interrupts.txt.

28Example:
29
30	i2c_gpio_expander@20{
31		#gpio-cells = <2>;
32		#interrupt-cells = <2>;
33		compatible = "semtech,sx1506q";
34		reg = <0x20>;
35		interrupt-parent = <&gpio_1>;
36		interrupts = <16 0>;
37
38		gpio-controller;
39		interrupt-controller;
40	};
