      1Raspberry Pi GPIO expander
      2
      3The Raspberry Pi 3 GPIO expander is controlled by the VC4 firmware. The
      4firmware exposes a mailbox interface that allows the ARM core to control the
      5GPIO lines on the expander.
      6
      7The Raspberry Pi GPIO expander node must be a child node of the Raspberry Pi
      8firmware node.
      9
     10Required properties:
     11
     12- compatible : Should be "raspberrypi,firmware-gpio"
     13- gpio-controller : Marks the device node as a gpio controller
     14- #gpio-cells : Should be two.  The first cell is the pin number, and
     15  the second cell is used to specify the gpio polarity:
     16  0 = active high
     17  1 = active low
     18
     19Example:
     20
     21firmware: firmware-rpi {
     22	compatible = "raspberrypi,bcm2835-firmware";
     23	mboxes = <&mailbox>;
     24
     25	expgpio: gpio {
     26		 compatible = "raspberrypi,firmware-gpio";
     27		 gpio-controller;
     28		 #gpio-cells = <2>;
     29	 };
     30};
