Hi Will,

Please consider these updates for arm-cmn. There are a couple of small
quality-of-life things at the start, while the bulk of the series
comprises a partial redesign of the driver to handle the direction in
which the CMN PMU design has evolved. This also cleans up and/or
finishes off a few incomplete bits of my original design, and culminates
in extending specific support to the first of the new IPs (expect a
couple more in the not-too-distant future once I've spent more time
poring through details, and our ACPI spec update gets published).

The final debugfs patch is not critical, but it's something I've been
maintaining for a while now, and a few other people have claimed to find
it useful as well.

Thanks,
Robin.
