Hi, Arnd,

According to your request, I have rebuilt two branches for PR (temporary):
https://github.com/sophgo/linux/tree/temp-riscv-sophgo-dt-for-next
https://github.com/sophgo/linux/tree/temp-arm-sophgo-dt-for-next

Please check whether it meets your requirements. Both branches are based 
on v6.16-rc1. If there is no problem, I will submit PRs using these two 
branches respectively.

It should be noted that about the commit "610f943a66be dt-bindings: soc: 
sophgo: Move SoCs/boards from riscv into soc, add SG2000" on 
temp-riscv-sophgo-dt-for-next. This change was originally made for 
SG2000/ARM, moving sophgo.yaml from the riscv directory to soc/sophgo 
for sharing between riscv and arm. Because this file will also be 
involved in subsequent changes for riscv, I placed it in 
temp-riscv-sophgo-dt-for-next.

Regards,

Chen
