This series adds resource-managed OPP API helpers and makes drivers to use them.
Changelog:
v2: - This is a continuation of the work that was started by Yangtao Li. Apparently Yangtao doesn't have time to finish it, so I (Dmitry Osipenko) picked up the effort since these patches are wanted by the NVIDIA Tegra voltage-scaling series that I'm working on.
- Fixed the double put of OPP resources.
- Dropped all patches that are unrelated to OPP API. I also dropped the Tegra memory patch since it doesn't apply now and because I plan to switch all Tegra drivers soon to a common tegra-specific OPP helper that will use the resource-managed OPP API anyways.
- Squashed couple patches into a single ones since there was no good reason to separate them.
- Added acks that were given to a couple of v1 patches.

I wonder if we still need to return opp_table from here, or a simple integer is fine.. The callers shouldn't be required to use the OPP table directly anymore I believe and so better simplify the return part of this and all other routines you are adding here..
If there is a user which needs the opp_table, let it use the regular non-devm variant.

Yes, please. I was thinking along the same lines, when I reviewed the mmc patch (patch9).

Kind regards Uffe

Indeed, that's a very good suggestion! The opp_table isn't needed by the devm users, I'll change it in v3, thanks!

Typo there.
Good catch! Although, that should be a patchwork fault since it auto-added acks when I downloaded v1 patches and I haven't changed them. I'll fix it in v3 or, if there won't be anything else to improve, then maybe Viresh could fix it up while applying patches.
