I believe all the current bcm2835 bindings use the compatible value as
the filename. I personally prefer this to picking a different "random"
name for the filenames. It means you only have to name the thing once,
and then use the same value for the compatible property and binding
document.

The HW mailbox seems like a different process to the upper-layer
protocols/message formats running over the top of it. Sure right now
the Pi has a single firmware, but do all bcm2835-based devices share
the same firmware? Is so, we'd be warranted in lumping the HW and
firmware protocol together, but I rather wonder whether e.g. the
bcm2835-based Roku uses the same firmware protocol?
