From: Mark Brown <broonie@linaro.org>
Since the OPP layer is a kernel library which has been converted to be
directly selectable by its callers rather than user selectable and
requiring architectures to enable it explicitly the ARCH_HAS_OPP symbol
has become redundant and can be removed. Do so.

Hi Simon, Mark,
Nice to see cleanups in this area. Reducing the number of Kconfig
symbols must be a good thing.
I'm not sure about the expected merge order for this kind of change vs
queued up stuff in the renesas git tree, but I believe the following
patch selects ARCH_HAS_OPP:

I propose that we fix that up by adding an incremental patch to
mach-shmobile via my renesas tree once the dependency (assuming there is
one) is in Linus's tree.

Yes, the conversion to make ARCH_HAS_OPP unused is in Raphael's tree for
the merge window. I'd expect this patch to end up going after the merge
window (or at the end I guess).

But it doesn't apply for me on top of the current Linus' tree.
Can you please rebase?

It probably depends on other people's trees too, I just killed all the

* [PATCH] PM / OPP: Remove ARCH_HAS_OPP

To: linux-arm-kernel
From: Mark Brown <broonie@linaro.org>
Since the OPP layer is a kernel library which has been converted to be
directly selectable by its callers rather than user selectable and
requiring architectures to enable it explicitly the ARCH_HAS_OPP symbol
has become redundant and can be removed. Do so.

Raphael, IIRC you said that you'd applied this but it seems not to have
appeared in -next. There's a few more references crept in, I'll try to
get them removed at source.

-Architectures that provide a SoC framework for OPP should select ARCH_HAS_OPP
-to make the OPP layer available.

OPP layer expects each domain to be represented by a unique device pointer. SoC
framework registers a set of initial OPPs per device with the OPP layer. This
list is expected to be an optimally small number typically around 5 per device.
