+GPIO and interrupt controller
+-----------------------------
+
+This hardware also acts as a GPIO controller and an interrupt
+controller.
+
+Consumers that would want to refer to one or the other (or both)
+should provide through the usual *-gpios and interrupts properties a
+cell with 3 arguments, first the number of the bank, then the pin
+inside that bank, and finally the flags for the GPIO/interrupts.
+
+Example:
+
+xio: gpio@38 {
+       compatible = "nxp,pcf8574a";
+       reg = <0x38>;
+
+       gpio-controller;
+       #gpio-cells = <2>;
+
+       interrupt-parent = <&pio>;
+       interrupts = <6 0 IRQ_TYPE_EDGE_FALLING>;
+       interrupt-controller;
+       #interrupt-cells = <2>;
+};

+       regulator-max-microvolt = <5000000>;
+       gpio = <&pio 7 6 GPIO_ACTIVE_HIGH>;
