1 SEMTECH SX150x GPIO expander bindings
6 - compatible: should be "semtech,sx1506q",
11 - reg: The I2C slave address for this device.
13 - interrupt-parent: phandle of the parent interrupt controller.
15 - interrupts: Interrupt specifier for the controllers interrupt.
17 - #gpio-cells: Should be 2. The first cell is the GPIO number and the
18 second cell is used to specify optional parameters:
19 bit 0: polarity (0: normal, 1: inverted)
21 - gpio-controller: Marks the device as a GPIO controller.
23 - interrupt-controller: Marks the device as a interrupt controller.
25 The GPIO expander can optionally be used as an interrupt controller, in
26 which case it uses the default two cell specifier as described in
27 Documentation/devicetree/bindings/interrupt-controller/interrupts.txt.
33 #interrupt-cells = <2>;
34 compatible = "semtech,sx1506q";
