So far all Exynos, S3C64xx and S5Pv210 clock units were selected by
respective SOC/ARCH Kconfig option. On a kernel built for selected
SoCs, this allowed to build only limited set of matching clock drivers.
However compile testing was not possible in such case as Makefile object
depent on SOC/ARCH option.
Add separate Kconfig options for each of them to be able to compile
test.

The patch look good to me, thanks.

I guess it's best now to merge it through your tree as it depends on
patches already sent to arm-soc? Next time it might be better to use
immutable branches right away to keep the clk changes in the clk
maintainer's tree.

At that time I had only one clk patch so I did not put it on separate
branch.
Anyway, this does not depend on the clkout patches and only minor patch
adjustement is needed. Cherry-pick can solve it (you would need to apply
on next/master and then cherry pick) or I can resend you one rebased on
linus/master.
There should be no conflicts when merging later into next or linus.
I propose you should take it via clk tree.
Best regards,
Krzysztof

Indeed, the conflict is minimal, I should have checked with git cherry-pick
once I found a branch where the patch applied cleanly. I have corrected
the typo an applied, thank you!
