Merge tag 'clk-v4.15-exynos-pm' of git://git.kernel.org/pub/scm/linux/kernel/git/snawrocki/clk into clk-next

Pull Samsung clk driver updates from Sylwester Nawrocki:

 - 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.
