Optional properties:
 - reset-gpios: GPIO specification for the RESET input. This is an
		active low signal to the PCA953x.

Example:


	gpio@20 {
		compatible = "nxp,pca9505";
		reg = <0x20>;
		pinctrl-names = "default";
		pinctrl-0 = <&pinctrl_pca9505>;
		interrupt-parent = <&gpio3>;
		interrupts = <23 IRQ_TYPE_LEVEL_LOW>;
	};
