One difference Exynos850 has w.r.t. other Exynos platforms in terms of
PM is that EL3 monitor handles TZ protection of CMU domains on
suspend/resume for us. This series enables PM support in clk-exynos850,
which was originally borrowed/extracted from clk-exynos5433 driver, and
also adds other missing bits, like adding those SMC calls, keeping PMU
clock always enabled and configuring MUX clocks before the suspend.
Dependencies inside of this series:
- patch #7 must go after #4
- patches 3-6 should go in the same order as in the series
- better to keep patche #1 and #2 before the rest of patches,
so that the driver and dts always use documented properties
