Changes since v3:

This patch series migrates the Samsung Exynos4 SoC clock code to adopt the
common clock framework. The use of Samsung specific clock structures has
been removed and all board support code has been updated. imx-style of
clock registration and lookup has been adopted for device tree based
exynos4 platforms.

I'd prefer to see if exynos4 and 5 were kept common here, and both transitioned
at the same time. Especially since there are no legacy boards for exynos5, it
would mean you could have a very clean transition there. What's the plan to
follow up with 5?

Ok. I have been looking into Exynos4 since Mr. Kim was already onto
Exynos5 common clock. Sure, we could do a cleaner Exynos4/5 common
clock series for v3.9. That would let both exynos4/5 to be built
together which otherwise this patch series would not allow.

What are the plans to remove legacy board files on exynos4 at this time
and switch them to DT-only? You could do it gradually like Stephen Warren
did on Tegra, with hooks that call out to some of the legacy code, but
configure the board through device tree and do away with the classic
machine descriptors, etc.

I did try this sometime back for exynos4210 based origen board. But
did not make much progress since certain portions require the older
samsung gpiolib support and exynos4210 mainline device tree support
has migrated to newer pinctrl framework. There is some work here to do
and I will work with Mr. Kim on this.

Thanks,
Thomas.
