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 [1] https://lkml.org/lkml/2021/10/22/978 [2] https://lkml.org/lkml/2021/11/9/660 [3] https://lkml.org/lkml/2021/10/25/818 Sam Protsenko (6): dt-bindings: clock: Add bindings for Exynos850 CMU_APM clk: samsung: exynos850: Implement CMU_APM domain dt-bindings: clock: Add bindings for Exynos850 CMU_CMGP clk: samsung: exynos850: Implement CMU_CMGP domain clk: samsung: exynos850: Register clocks early clk: samsung: exynos850: Keep some crucial clocks running .../clock/samsung,exynos850-clock.yaml | 38 ++ drivers/clk/samsung/clk-exynos850.c | 327 ++++++++++++++++-- include/dt-bindings/clock/exynos850.h | 46 ++- 3 files changed, 387 insertions(+), 24 deletions(-)
