Please do not send 10 separate patches, but one patchset for given
subsystem.

Hi Krzysztof,

Thanks a lot for your review.

Can we send one patch that includes all nodes that are existing
NPCM8xx drivers in the kernel, or do you prefer a patchset that
contains patches for each NPCM8xx driver?

Thanks,

Tomer

When I send a patchset should I add the reply-to tags for all of these
previous reviews? Or just resend as a new review?

I don't understand what you are asking me. You NEVER add manually
in-reply to. You should use either git send-email or b4 or patman.
Nothing else, no manual edits, no weird headers.

If you ask about review, that's entirely different topic - see
submitting patches. BTW, kernel docs also explain how to actually send
these emails...

Best regards,
Krzysztof
