    1 Broadcom BCM2835 VideoCore mailbox IPC
    2 
    3 Required properties:
    4 
    5 - compatible:   Should be "brcm,bcm2835-mbox"
    6 - reg:          Specifies base physical address and size of the registers
    7 - interrupts:   The interrupt number
    8                   See bindings/interrupt-controller/brcm,bcm2835-armctrl-ic.txt
    9 - #mbox-cells:  Specifies the number of cells needed to encode a mailbox
   10                   channel. The value shall be 0, since there is only one
   11                   mailbox channel implemented by the device.
   12 
   13 Example:
   14 
   15 mailbox: mailbox@7e00b880 {
   16         compatible = "brcm,bcm2835-mbox";
   17         reg = <0x7e00b880 0x40>;
   18         interrupts = <0 1>;
   19         #mbox-cells = <0>;
   20 };
   21 
   22 firmware: firmware {
   23         compatible = "raspberrypi,firmware";
   24         mboxes = <&mailbox>;
   25         #power-domain-cells = <1>;
