OK.

Tony, updated pull request below.  This includes all the TWL depencies
merged from the 'topic/twl' tag in Mark's tree.

Has this been lost now? It seems regulator parts got merged, but
voltage parts are missing from Arnd's pull requests and are not
showing up in linux-next.
Was looking forward for voltage control in 3.4 to achieve higher clock
rates on our aging OMAP3 hardware.

Sounds like this is something we should get merged early to arm-soc
tree after the merge window.

Not lost, just delayed.   Due to problems in working out the
dependencies with the regulator core, this pull request was too late to
make it for v3.4.

Pulled in this into pm-regulator branch finally.
