[PATCH 0/3] mailbox: New mailbox driver for ST

This set provides support for ST's Mailbox IP.

In order to save IRQ lines, current platforms have been only been
given a single interrupt for receiving messages from co-processors.
The best way to work around this limitation is to use Mailbox 1
(A9) as the receiving MB.  This driver/binding then has the ability
to map the remaining Mailboxes back to Mailbox 1 where threaded
interrupts are used to extract data to send back to the user.
