First off, my apologies to everyone for not knowing how to check for
existing upstream request for the LTC2305 device before working on it
and wasting everyone's review time. It's a learning experience for me.

But it's still awesome to see how both ended up with almost the same
code after review.

I'll reply to Kyle's series to ask if the delay for LTC2305 could be included.

Kind regards,
Carlos
