Pull Exynos5433 SoC updates from Sylwester Nawrocki:

 - addition of missing documentation and DT properties for the CMU_AUD
   block source clocks,
 - correction of CMU_FSYS parent clock definition,
 - marking as critical clocks which have to be enabled in order
   to access control registers of child CMUs.

* tag 'clk-v4.10-exynos5433' of git://linuxtv.org/snawrocki/samsung:
  clk: exynos5433: Mark some clocks as critical
  clk: exynos5433: Add documentation for the audio block parent clocks
  clk: exynos5433: Fix parent clocks for FSYS block
