Merge tag 'clk-v5.17-samsung' of https://git.kernel.org/pub/scm/linux/kernel/git/snawrocki/clk into clk-samsung
Pull Samsung clk driver updates from Sylwester Nawrocki: - removal of all remaining uses of __clk_lookup() in drivers/clk/samsung - refactoring of the CPU clocks registration to use common interface - an update of the Exynos850 driver (support for more clock domains) required by the E850-96 development board - initial clock driver for the Exynos7885 SoC (Samsung Galaxy A8) * tag 'clk-v5.17-samsung' of https://git.kernel.org/pub/scm/linux/kernel/git/snawrocki/clk: clk: samsung: Add initial Exynos7885 clock driver clk: samsung: clk-pll: Add support for pll1417x clk: samsung: Make exynos850_register_cmu shared dt-bindings: clock: Document Exynos7885 CMU bindings dt-bindings: clock: Add bindings definitions for Exynos7885 CMU clk: samsung: exynos850: Add missing sysreg clocks dt-bindings: clock: Add bindings for Exynos850 sysreg clocks clk: samsung: exynos850: Register clocks early clk: samsung: exynos850: Keep some crucial clocks running clk: samsung: exynos850: Implement CMU_CMGP domain dt-bindings: clock: Add bindings for Exynos850 CMU_CMGP clk: samsung: exynos850: Implement CMU_APM domain dt-bindings: clock: Add bindings for Exynos850 CMU_APM clk: samsung: Update CPU clk registration clk: samsung: Remove meaningless __init and extern from header files clk: samsung: remove __clk_lookup() usage dt-bindings: clock: samsung: add IDs for some core clocks
