Subject: [PATCH 0/6] clk: samsung: exynos850: Clock driver improvements

This cumulative series supersedes next patches/series:
  1. CMU_APM domain implementation series [1]
  2. CMU_CMGP domain implementation series [2]
  3. "Register clocks early" patch [3]

with changes as follows:
  - add "Keep some crucial clocks running" patch [6/6]
  - enable CMU_PERI parent clock early
  - move bindings headers changes into bindings doc patches

Tested:
  - CMU_TOP is registered before CMU_PERI
  - CMU_PERI parent clock is enabled early and successfully, and running
    before any access to CMU_PERI registers
  - kernel boots successfully without "clk_ignore_unused" param
  - MCT timer works fine and doesn't panic during bootup
