The commit adding the bindings for the compatible "sophgo,sg2002-clint"
has been applied to Daniel Lezcano git tree. This commit may trigger the
bots because of this missing binding.

I got the following waring:
arch/riscv/boot/dts/sophgo/sg2002.dtsi:20.28-25.5: Warning (simple_bus_reg): /soc/pinctrl@3008000: simple-bus unit address format error, expected "3001000"

Could you send a fix patch?

Regards,
Inochi

I wanted to say, that the comment above is no longer relevant because 
Daniel Lezcano's branch was applied in 6.11.

Best regards,
