-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>;
- };
-};
