Add basic support for the Axis ARTPEC-8 SoC which contains quad-core Cortex-A53 CPU and other several IPs. This SoC is an Axis-designed chipset used in surveillance camera products such as the AXIS Q1656-LE and AXIS Q3538-LVE. This ARTPEC-8 SoC has a variety of Samsung-specific IP blocks and Axis-specific IP blocks and SoC is manufactured by Samsung Foundry. List of Samsung-provided IPs: - UART - Ethernet (Vendor: Synopsys) - SDIO - SPI - HSI2C - I2S - CMU (Clock Management Unit) - Pinctrl (GPIO) - PCIe (Vendor: Synopsys) - USB (Vendor: Synopsys) List of Axis-provided IPs: - VIP (Image Sensor Processing IP) - VPP (Video Post Processing) - GPU - CDC (Video Encoder) This patch series includes below changes: - CMU (Clock Management Unit) driver and its bindings - GPIO pinctrl configuration and its bindings - Basic Device Tree for ARTPEC-8 SoC and boards The patch series has been tested on the ARTPEC-8 EVB with Linux v6.15-rc5 and intended to be merged via the `arm-soc` tree. --- Changes in v3: - Rebased patchset on linux-samsung-soc "for-next" branch which includes round_rate() drop - Add CPU mask in dtsi patch #8 Link to v2: https://lore.kernel.org/all/20250821123310.94089-1-ravi.patel@xxxxxxxxxxx/ --- Changes in v2: - Update SoB sections in all patches - Update the copyright year to 2025 - Add CMU abbreviation description - Merge dt-bindings patch 01 and 02 into single patch - Modify yaml file to fit coding style in CMU - Modify clock-names - Reorder config macros to fit coding style - Remove the unused macro in clock driver code - Squash all clock driver patches (4 to 10) into single patch - Split yaml conversion patch translation and add ARTPEC-8 SoC - Remove "clock-frequency" property from cpu node in dtsi - Remove the "status" property in dts and dtsi - Reorder the DTS and pin nodes to follow the alphabetical and DTS coding style - Change items property in axis.yaml - Move dts files to exynos folder - Removed ARCH_ARTPEC8 from platform Kconfig - Add pattern in MAINTAINER file - Merge dtsi and pinctrl dtsi file - Split board dts file Link to v1: https://lore.kernel.org/all/20250710002047.1573841-1-ksk4725@xxxxxxxxxx/ NOTE: The first version has been sent by Coasia. After that, it has been agreed between Coasia and Samsung that Samsung will take ownership of upstreaming ARTPEC-8 and ARTPEC-9 platforms. --- Hakyeong Kim (3): dt-bindings: clock: Add ARTPEC-8 clock controller clk: samsung: Add clock PLL support for ARTPEC-8 SoC clk: samsung: artpec-8: Add initial clock support for ARTPEC-8 SoC Ravi Patel (1): dt-bindings: arm: Convert Axis board/soc bindings to json-schema SeonGu Kang (3): dt-bindings: pinctrl: samsung: Add compatible for ARTPEC-8 SoC pinctrl: samsung: Add ARTPEC-8 SoC specific configuration arm64: dts: axis: Add ARTPEC-8 Grizzly dts support SungMin Park (3): dt-bindings: arm: axis: Add ARTPEC-8 grizzly board arm64: dts: exynos: axis: Add initial ARTPEC-8 SoC support arm64: defconfig: Enable Axis ARTPEC SoC .../devicetree/bindings/arm/axis.txt | 13 - .../devicetree/bindings/arm/axis.yaml | 36 + .../bindings/clock/axis,artpec8-clock.yaml | 213 ++++ .../bindings/pinctrl/samsung,pinctrl.yaml | 1 + MAINTAINERS | 12 + arch/arm64/Kconfig.platforms | 7 + arch/arm64/boot/dts/exynos/Makefile | 1 + arch/arm64/boot/dts/exynos/axis/Makefile | 4 + .../boot/dts/exynos/axis/artpec-pinctrl.h | 36 + .../boot/dts/exynos/axis/artpec8-grizzly.dts | 35 + .../boot/dts/exynos/axis/artpec8-pinctrl.dtsi | 120 ++ arch/arm64/boot/dts/exynos/axis/artpec8.dtsi | 244 ++++ arch/arm64/configs/defconfig | 1 + drivers/clk/samsung/Makefile | 1 + drivers/clk/samsung/clk-artpec8.c | 1044 +++++++++++++++++ drivers/clk/samsung/clk-pll.c | 128 +- drivers/clk/samsung/clk-pll.h | 2 + .../pinctrl/samsung/pinctrl-exynos-arm64.c | 50 + drivers/pinctrl/samsung/pinctrl-exynos.h | 10 + drivers/pinctrl/samsung/pinctrl-samsung.c | 2 + drivers/pinctrl/samsung/pinctrl-samsung.h | 1 + include/dt-bindings/clock/axis,artpec8-clk.h | 169 +++ 22 files changed, 2116 insertions(+), 14 deletions(-) delete mode 100644 Documentation/devicetree/bindings/arm/axis.txt create mode 100644 Documentation/devicetree/bindings/arm/axis.yaml create mode 100644 Documentation/devicetree/bindings/clock/axis,artpec8-clock.yaml create mode 100644 arch/arm64/boot/dts/exynos/axis/Makefile create mode 100644 arch/arm64/boot/dts/exynos/axis/artpec-pinctrl.h create mode 100644 arch/arm64/boot/dts/exynos/axis/artpec8-grizzly.dts create mode 100644 arch/arm64/boot/dts/exynos/axis/artpec8-pinctrl.dtsi create mode 100644 arch/arm64/boot/dts/exynos/axis/artpec8.dtsi create mode 100644 drivers/clk/samsung/clk-artpec8.c create mode 100644 include/dt-bindings/clock/axis,artpec8-clk.h -- 2.49.0
