For these SoCs, the CPUs share the same clock by cluster, so actually the clock management is done at cluster level. As for the other Armada 7K/8K clocks it is possible to have multiple AP so here again we need to have unique name: the purpose of the second patch is to share a common code which will be used in 3 drivers. The last 2 patch enable the driver at dt and platform level and will be applied through the mvebu subsystem. Changelog v2->v3: - Add back the first patch documenting the binding Changelog v1->v2: - Header cleanup - Use unsigned int instead of it for cluster member of the ap_cpu_clk struct - Use clk_hw instead of clk - Use regmap_read_poll_timeout - Use for_each_of_cpu_node - Remove unnecessary WARN_ON() - Remove headers from armada_ap_cp_helper.h - Few other minor cleanup Gregory CLEMENT (6): dt-bindings: ap806: add the cluster clock node in the syscon file clk: mvebu: add helper file for Armada AP and CP clocks clk: mvebu: add CPU clock driver for Armada 7K/8K clk: mvebu: ap806: Fix clock name for the cluster arm64: marvell: enable the Armada 7K/8K CPU clk driver arm64: dts: marvell: Add cpu clock node on Armada 7K/8K .../arm/marvell/ap806-system-controller.txt | 22 ++ arch/arm64/Kconfig.platforms | 1 + .../boot/dts/marvell/armada-ap806-quad.dtsi | 4 + arch/arm64/boot/dts/marvell/armada-ap806.dtsi | 6 + drivers/clk/mvebu/Kconfig | 8 + drivers/clk/mvebu/Makefile | 2 + drivers/clk/mvebu/ap-cpu-clk.c | 259 ++++++++++++++++++ drivers/clk/mvebu/ap806-system-controller.c | 24 +- drivers/clk/mvebu/armada_ap_cp_helper.c | 30 ++ drivers/clk/mvebu/armada_ap_cp_helper.h | 11 + drivers/clk/mvebu/cp110-system-controller.c | 32 +-- 11 files changed, 357 insertions(+), 42 deletions(-) create mode 100644 drivers/clk/mvebu/ap-cpu-clk.c create mode 100644 drivers/clk/mvebu/armada_ap_cp_helper.c create mode 100644 drivers/clk/mvebu/armada_ap_cp_helper.h
