Hi Stephen, Mike,
This change set is based off of your clk-pm-runtime branch, I needed to
do it that way as there were dependencies on the newly added clk runtime
PM feature. In this tag there is also a fix commit related to changes
introduced in the clk-pm-runtime branch. There will be a merge conflict,
you can find the conflict resolution hint below.
The following changes since commit ae432a9b314e07d486acfadc4df2f922721e6757:

clk: samsung: Add a separate driver for Exynos4412 ISP clocks (2017-10-16 11:25:50 +0200)
----------------------------------------------------------------
clk/samsung updates for v4.15, part 2
- An addition of separate driver for the Exynos 4412 ISP CMU, needed
to model and properly handle the clock controller's dependencies
on the ISP power domain.
- Adding __maybe_unused attributes to the exynos5433_cmu_{suspend,
resume} ops to suppress compiler warnings with CONFIG_PM disabled.
----------------------------------------------------------------
Arnd Bergmann (1):
clk: samsung: exynos5433: mark PM functions as __maybe_unused
Marek Szyprowski (3):
clk: samsung: Instantiate Exynos4412 ISP clocks only when available
clk: samsung: Add dt bindings for Exynos4412 ISP clock controller
