My local dev branch is usually available at:
git://nv-tegra.nvidia.com/user/swarren/linux-2.6 linux-next_common

The local patches are mostly regulator support work-in-progress at the
moment, so nothing to do with clocks, except one minor warning fix.

I see you've posted v3; I assume that means you've found/fixed the
issues - I'll go test.
