Well, feel free to add: Acked-by: Marek Szyprowski <m.szyprowski@xxxxxxxxxxx> to v3 (the whole patchset). The only remark I have is not strictly related to this patchset, but the code that is already in drivers/clk/samsung/clk-exynos-arm64.c. Playing with GATE_ENABLE_HWACG/GATE_MANUAL is not strictly specific to all Exynos ARM64 SoCs. GATE_OFF_START/GATE_OFF_END and the enable register bits are something specific to recent Exynos SoCs (like 7885/850/auto9) and don't fit well into the generic arm64 clk PM code, but I don't have a good idea how to move it to the respective clk drivers and keep it simple.
