   riscv: dts: sophgo: Add Milk-V Duo 256M board support (2026-08-04 
18:04:32 +0800)

RISC-V Devicetrees for v7.3

Sophgo:

The changes of this PR are all for CV18xx serials.
There are three major changes. The first is to allow
DMA multiplexer setting channel number for DMA controller;
the second is to add initial RISC-V support for "Duo S"
board, which uses SG2000, a dual-arch SoC (RISC-V and
ARM64); the third is to add support for "Duo 256M"
board, another dev-board based on SG2002 SoC.
