Subject: [PATCH v3 0/5] LPC/MBOX work

I thought I would put it one final time on here mostly because
patch 5/5, the mbox driver, got quite a rework today thanks for the
review Ben!

Notable differences is that I've completely ditched the ioctl() in
favour of arbitrary reads and writes. This gives userspace the
ability to touch only one reg which was the aim of the ioctl() anyway.
The userspace complexity is similar, or perhaps a little more simple,
no sacrifice there.

In the process of having the kernel allow access of any sized
read/write to all 16 of the data regs I realise that some of the
intended protocol had snuck in, or rather hadn't been completed
removed, that got addressed too.

Also added a mutex to avoid multiple writers.

Thanks,

Cyril
