Subject: Re: [PATCH v2 0/4] riscv: sophgo: cv18xx: Add reset generator support

hi, Inochi,

Judging from the title of the email, your patch should be for supporting 
all cv18xx series socs, including cv1800b/SG2002 (formerly 
CV181xC)/SG2000 (formerly CV181xH), right?
I see Alex is submiting a PR to support reset for SG2000 [1], so suggest 
you discuss with Alex and merge your work with his to avoid forking.

Alex Sverdlin, I see you are also in the to-list, what's your point?

Thanks,

Chen
