Broadcom BCM2835 VideoCore mailbox IPC
Required properties:
- compatible: Should be "brcm,bcm2835-mbox"
- reg: Specifies base physical address and size of the registers
- interrupts: The interrupt number
See bindings/interrupt-controller/brcm,bcm2835-armctrl-ic.txt
- #mbox-cells: Specifies the number of cells needed to encode a mailbox
channel. The value shall be 0, since there is only one
mailbox channel implemented by the device.
Example:
mailbox: mailbox@7e00b800 {
compatible = "brcm,bcm2835-mbox";
reg = <0x7e00b880 0x40>;
interrupts = <0 1>;
#mbox-cells = <0>;
};
firmware: firmware {
compatible = "raspberrypi,firmware";
mboxes = <&mailbox>;
#power-domain-cells = <1>;
};
