This series switches the Milk-V Duo board to the upstream CV1800B devicetree.
Patch 1 adds the missing clock-controller compatible used by the upstream CV1800B devicetree. Patch 2 switches the board defconfig to CONFIG_OF_UPSTREAM and adds a small U-Boot override to keep Ethernet enabled. Patch 3 removes the now-unused local Milk-V Duo devicetree files. Tested on Milk-V Duo: - U-Boot boots with the upstream control FDT - serial console works - MMC is detected and can read the SD card - Ethernet is probed and DHCP/TFTP work - Linux boots via TFTP with Image, initramfs and DTB Build-tested: - make CROSS_COMPILE=riscv64-linux-gnu- milkv_duo_defconfig - make CROSS_COMPILE=riscv64-linux-gnu- -j$(nproc) Signed-off-by: Zhuxu Ran <[email protected]> --- Zhuxu Ran (3): clk: sophgo: cv1800b: Add cv1800b clock compatible riscv: milkv_duo: Use upstream devicetree riscv: dts: milkv_duo: Drop local devicetree files arch/riscv/dts/Makefile | 1 - arch/riscv/dts/cv1800b-milkv-duo-u-boot.dtsi | 12 ++++++ arch/riscv/dts/cv1800b-milkv-duo.dts | 64 ---------------------------- arch/riscv/dts/cv1800b.dtsi | 22 ---------- configs/milkv_duo_defconfig | 3 +- drivers/clk/sophgo/clk-cv1800b.c | 1 + 6 files changed, 15 insertions(+), 88 deletions(-) --- base-commit: 780084d7c07f511da4a39b43277c573156ed42e0 change-id: 20260702-milkv-duo-upstream-dts-b54aed41fc61 Best regards, -- Zhuxu Ran <[email protected]>
