Merge tag 'clk-v4.9-samsung' of git://linuxtv.org/snawrocki/samsung into clk-next

Pull samsung clk driver updates from Sylwester Nawrocki:

In addition to a few clean up and code consolidation patches this
includes:
- addition of sound subsystem related clocks for Exynos5410 SoC
  (EPLL, PDMA) and support for "samsung,exynos5410-audss-clock"
  compatible in the clk-exynos-audss driver,
- addition of DRAM controller related clocks for exynos5420,
- MAINTAINERS update adding Chanwoo Choi as the Samsung SoC
  clock drivers co-maintainer.

* tag 'clk-v4.9-samsung' of git://linuxtv.org/snawrocki/samsung:
  clk: samsung: Add support for EPLL on exynos5410
