-Raspberry Pi GPIO expander
-
-The Raspberry Pi 3 GPIO expander is controlled by the VC4 firmware. The
-firmware exposes a mailbox interface that allows the ARM core to control the
-GPIO lines on the expander.
-
-The Raspberry Pi GPIO expander node must be a child node of the Raspberry Pi
-firmware node.
-
-Required properties:
-
-- compatible : Should be "raspberrypi,firmware-gpio"
-- gpio-controller : Marks the device node as a gpio controller
-- #gpio-cells : Should be two.  The first cell is the pin number, and
-  the second cell is used to specify the gpio polarity:
-  0 = active high
-  1 = active low
-
-Example:
-
-firmware: firmware-rpi {
-	compatible = "raspberrypi,bcm2835-firmware";
-	mboxes = <&mailbox>;
-
-	expgpio: gpio {
-		 compatible = "raspberrypi,firmware-gpio";
-		 gpio-controller;
-		 #gpio-cells = <2>;
-	 };
-};
