No function calls, just use regulators_node. What is unclear about the

I don't understand what you mean by "regulators_node".

"grep -R regulators_node *" in the kernel source tree returns no results,
nor does http://lxr.free-electrons.com/ident?i=regulators_node

You need to develop against current versions of the kernel, this is
something that was merged into Linus' tree during the merge window.

Is this an absolute show-stopper for you?

With some effort I could move from our current 3.15 to 3.17, but even that
wouldn't be recent enough then. I can justify spending a few days on getting
the driver integrated into mainline, even if the initial version cost less
than that; but moving everything to mainline is going to take weeks and the
boss is definitely going to say "no" to that.

More important than that: Since this chip powers the IO banks, we need it for our own products, and hence it has to work (also) on the current 3.15 kernel. Using APIs from 3.18 wouold render the driver useless to ourselves.
