This is my fault, I copied the wrong url. The right patch is https://lore.kernel.org/r/20240217144826.3944-1-jszhang@kernel.org.

I think you miss nothing. Using huashan-pi dts as a temporary solution is just because they are both CV181X series. Since only a few peripherals are supported, it is also OK to use duo dts with local change. They're not significantly different. This is also the reason I did not prepare any patch for the new board. (such as lichee RV NANO, duo 256).
