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 .../clock/samsung,exynos850-clock.yaml | 13 ++ arch/arm64/boot/dts/exynos/exynos850.dtsi | 1 - drivers/clk/samsung/clk-exynos-arm64.c | 39 +++++- drivers/clk/samsung/clk-exynos850.c | 112 ++++++++++++++++-- 4 files changed, 153 insertions(+), 12 deletions(-) -- 2.39.2
