The third version was sent more than 3 months without any relevant feedback since this end of decembe last year. 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 v3->v4: - Rebased on v5.1-rc1 - Mention in the binding that a reg property can be used to make the device tree maintainer happy in the hope that there will be finally a review on this patch blocking the whole series. 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 | 25 ++ 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, 360 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
