1 SEMTECH SX150x GPIO expander bindings
6 - compatible: should be "semtech,sx1506q",
10 - reg: The I2C slave address for this device.
12 - interrupt-parent: phandle of the parent interrupt controller.
14 - interrupts: Interrupt specifier for the controllers interrupt.
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)
20 - gpio-controller: Marks the device as a GPIO controller.
22 - interrupt-controller: Marks the device as a interrupt controller.
24 The GPIO expander can optionally be used as an interrupt controller, in
25 which case it uses the default two cell specifier as described in
26 Documentation/devicetree/bindings/interrupt-controller/interrupts.txt.
32 #interrupt-cells = <2>;
