Hi Inochi

Thanks for your help!

Indeed, I was using the "defconfig" config. Too used to having 
everything working with this configuration on RISC-V :-/

Gotcha for the CONFIG_CLK_SOPHGO_CV1800 setting. However, I'm confused. 
Why is this setting available in linux-next, but neither in 
git.kernel.org/pub/scm/linux/kernel/git/riscv/linux.git ("master" and 
"for-next") nor in github.com/sophgo/linux.git ("master" and "for-next") ?

What's the tree used to push to linux-next?

Cheers
Michael.
