this device provides. It might be better to mention the functionality
the System MMU supports and refer to other subsystem documents (e,g,
clocking and power control) for details.

Can I suggest rewriting the last two sentences to:
The master device node must correctly specify at least one
SystemMMU. A master device may have more than one System MMU.
BTW, is there a difference between "master device" and "master
peripheral device" that I'm not aware of? Perhaps use just one of
those expressions in this document, not both if they are the same
thing (which is what I assumed).
cheers,
