When you say that you've split them, do you mean each DT doc, as I
don't think this is the way to go. I'm happy to listen to other
people's opinions, but I think all of the .../mailbox/brcm,bcm2835-
files should be amalgamated.

Rename these files to conform to the current naming convention. In
-next we currently have 'altera-mailbox.txt' and 'omap-mailbox.txt',
so 'bcm2835-mbox.txt' seems appropriate.

Binding documents are much easier to read if the property names and
descriptions are seperated with tabs.
- compatible : Should be "brcm,bcm2835-mbox"
- reg : Specifies base physical address and size of the registers
- interrupts : The interrupt number
[See ../interrupt-controller/brcm,bcm2835-armctrl-ic.txt]
- #mbox-cells : Specifies the number of cells needed to encode a
mailbox channel. The value shall be 1
... don't you think? Also notice the consistency of no '.'s and the
bracketing of the [See ...] statement.

It would be good to see the client examples here as well. Please consider
pulling in brcm,bcm2835-mbox-power.txt and brcm,bcm2835-mbox-property.txt.
