MAINTAINERS file has "K: sophgo" entry already, I suppose new files will fall into this category? That's why I've ignored this specific checkpatch warning in all patches.

This series adds very basic support for Milk-V Duo Module 01 EVB [1] in arm64 mode. The SoC (SG2000) is dual-arch, RiscV and ARM64, the latter has been chosen because the upstream toolchain can be utilized. Sophgo SG2000 seems to be a continuation of the Cvitek CV18xx series, same peripherals with an addition of ARM64 core. Therefore it would be beneficial not to copy-paste the peripherals' device-tree, but rather split the most suitable riscv DT into ARCH-specific and peripherals parts and just include the latter on the arm64 side. This series adds the device-tree for Milk-V Duo Module 01 EVB, which in turn contains Milk-V Duo Module 01 (separate .dtsi) on it, which has SG2000 SoC inside (separate .dtsi). This series has been tested with Sophgo-provided U-Boot binary [2]: it boots from SD card; pinctrl, serial, GPIO drivers are functional (same as for RiscV-based CV18xx SoCs). Partial SoC documentation is available [3]. This series lacks the support of: - USB - Audio - Ethernet - WiFi - Bluetooth - eMMC - Video - "reboot" functionality It would probably make sense that the series will go into ARM SOC tree. Changelog: v2: - dropped all patches related to the new reboot driver and corresponding DT and bindings; - grouped DT-related and config-related patches together; - added patch moving sophgo.yaml from riscv into soc (to share it with ARM); added SG2000 SoC and Milk-V Duo Module 01 EVB into it; - other changes are documented in the corresponding patches; [1] https://milkv.io/docs/duo/getting-started/duo-module-01 [2] https://github.com/milkv-duo/duo-buildroot-sdk-v2/releases/ [3] https://github.com/sophgo/sophgo-doc/releases/download/sg2000-trm-v1.01/sg2000_trm_en.pdf Alexander Sverdlin (7): riscv: dts: sophgo: cv18xx: Move RiscV-specific part into SoCs' .dtsi files dt-bindings: soc: sophgo: Move SoCs/boards from riscv into soc, add SG2000 arm64: dts: sophgo: Add initial SG2000 SoC device tree arm64: dts: sophgo: Add Duo Module 01 arm64: dts: sophgo: Add Duo Module 01 Evaluation Board arm64: Add SOPHGO SOC family Kconfig support arm64: defconfig: Enable rudimentary Sophgo SG2000 support .../{riscv => soc/sophgo}/sophgo.yaml | 7 +- arch/arm64/Kconfig.platforms | 6 ++ arch/arm64/boot/dts/Makefile | 1 + arch/arm64/boot/dts/sophgo/Makefile | 2 + .../sophgo/sg2000-milkv-duo-module-01-evb.dts | 31 +++++++ .../sophgo/sg2000-milkv-duo-module-01.dtsi | 85 +++++++++++++++++ arch/arm64/boot/dts/sophgo/sg2000.dtsi | 75 +++++++++++++++ arch/arm64/configs/defconfig | 5 + arch/riscv/boot/dts/sophgo/cv1800b.dtsi | 64 ++++++++++--- arch/riscv/boot/dts/sophgo/cv1812h.dtsi | 64 ++++++++++--- arch/riscv/boot/dts/sophgo/cv181x.dtsi | 2 +- arch/riscv/boot/dts/sophgo/cv18xx-cpu.dtsi | 57 ++++++++++++ arch/riscv/boot/dts/sophgo/cv18xx.dtsi | 91 +++++-------------- arch/riscv/boot/dts/sophgo/sg2002.dtsi | 64 ++++++++++--- 14 files changed, 451 insertions(+), 103 deletions(-) rename Documentation/devicetree/bindings/{riscv => soc/sophgo}/sophgo.yaml (80%) create mode 100644 arch/arm64/boot/dts/sophgo/Makefile create mode 100644 arch/arm64/boot/dts/sophgo/sg2000-milkv-duo-module-01-evb.dts create mode 100644 arch/arm64/boot/dts/sophgo/sg2000-milkv-duo-module-01.dtsi create mode 100644 arch/arm64/boot/dts/sophgo/sg2000.dtsi create mode 100644 arch/riscv/boot/dts/sophgo/cv18xx-cpu.dtsi
