- - gpio-controller: if used as gpio expander.
- - #gpio-cells: if used as gpio expander.
- - interrupt-controller: if to be used as interrupt expander.
- - #interrupt-cells: if to be used as interrupt expander.
-
-Optional properties:
- - interrupts: interrupt specifier for the device's interrupt output.
- - reset-gpios: GPIO specification for the RESET input. This is an
- active low signal to the PCA953x.
- - vcc-supply: power supply regulator.

-Example:
-
-

- reg = <0x20>;
- pinctrl-names = "default";
- pinctrl-0 = <&pinctrl_pca9505>;
- gpio-controller;
- #gpio-cells = <2>;
- interrupt-parent = <&gpio3>;
- interrupts = <23 IRQ_TYPE_LEVEL_LOW>;
- };
