 - 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:





	gpio@20 {

		compatible = "nxp,pca9505";

		reg = <0x20>;

		pinctrl-names = "default";

		pinctrl-0 = <&pinctrl_pca9505>;

		gpio-controller;

		#gpio-cells = <2>;

		interrupt-parent = <&gpio3>;

		interrupts = <23 IRQ_TYPE_LEVEL_LOW>;

	};





Example with Interrupts:





	gpio99: gpio@22 {

		compatible = "nxp,pcal6524";

		reg = <0x22>;

		interrupt-parent = <&gpio6>;

		interrupts = <1 IRQ_TYPE_EDGE_FALLING>;	/* gpio6_161 */

		interrupt-controller;

		#interrupt-cells = <2>;

		vcc-supply = <&vdds_1v8_main>;

		gpio-controller;

		#gpio-cells = <2>;

		gpio-line-names =

			"hdmi-ct-hpd", "hdmi.ls-oe", "p02", "p03", "vibra", "fault2", "p06", "p07",

			"en-usb", "en-host1", "en-host2", "chg-int", "p14", "p15", "mic-int", "en-modem",

			"shdn-hs-amp", "chg-status+red", "green", "blue", "en-esata", "fault1", "p26", "p27";

	};



	ts3a227@3b {

		compatible = "ti,ts3a227e";

		reg = <0x3b>;

		interrupt-parent = <&gpio99>;

		interrupts = <14 IRQ_TYPE_EDGE_RISING>;

		ti,micbias = <0>;	/* 2.1V */

	};
