-* Microchip PIC32 GPIO devices (PIO).
-
-Required properties:
- - compatible: "microchip,pic32mzda-gpio"
- - reg: Base address and length for the device.
- - interrupts: The port interrupt shared by all pins.
- - gpio-controller: Marks the port as GPIO controller.
- - #gpio-cells: Two. The first cell is the pin number and
-   the second cell is used to specify the gpio polarity as defined in
-   defined in <dt-bindings/gpio/gpio.h>:
-      0 = GPIO_ACTIVE_HIGH
-      1 = GPIO_ACTIVE_LOW
-      2 = GPIO_OPEN_DRAIN
- - interrupt-controller: Marks the device node as an interrupt controller.
- - #interrupt-cells: Two. The first cell is the GPIO number and second cell
-   is used to specify the trigger type as defined in
-   <dt-bindings/interrupt-controller/irq.h>:
-      IRQ_TYPE_EDGE_RISING
-      IRQ_TYPE_EDGE_FALLING
-      IRQ_TYPE_EDGE_BOTH
- - clocks: Clock specifier (see clock bindings for details).
- - microchip,gpio-bank: Specifies which bank a controller owns.
- - gpio-ranges: Interaction with the PINCTRL subsystem.
-
-Example:
-
-/* PORTA */
-gpio0: gpio0@1f860000 {
-	compatible = "microchip,pic32mzda-gpio";
-	reg = <0x1f860000 0x100>;
-	interrupts = <118 IRQ_TYPE_LEVEL_HIGH>;
-	#gpio-cells = <2>;
-	gpio-controller;
-	interrupt-controller;
-	#interrupt-cells = <2>;
-	clocks = <&rootclk PB4CLK>;
-	microchip,gpio-bank = <0>;
-	gpio-ranges = <&pic32_pinctrl 0 0 16>;
-};

-keys {
-	...
-
-	button@sw1 {
-		label = "ESC";
-		linux,code = <1>;
-		gpios = <&gpio0 12 0>;
