[PATCH 0/7] clk: samsung: Enable PM in Exynos850 clk driver

[Sam Protsenko <semen.protsenko@linaro.org>]

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

Sam Protsenko (7):
  dt-bindings: clock: exynos850: Add power-domains property
  dt-bindings: clock: exynos850: Add tzpc property
  clk: samsung: Implement PM SMC calls for ARM64 Exynos SoCs
  clk: samsung: exynos850: Make PMU_ALIVE_PCLK critical
  clk: samsung: exynos850: Add suspend state for all CMUs
  clk: samsung: exynos850: Enable PM support in clk-exynos850
  arm64: dts: exynos: Remove clock from Exynos850 pmu_system_controller
