SubjectRe: [PATCH v2 5/5] MAINTAINERS: Add Actions Semi S900 pinctrl entries

OK let's keep it like it is then, one entry.

I am sorry if you feel you are being treated unfairly.

I can't help to think about the old IT project motto "always
calculate to throw one version away". We are always going to
have a bit of collateral damage around out sometimes chaotic
and unstructured development process.

I haven't seen this S500 patch posted anywhere on the pin control
official mailing list. As subsystem maintainer I have a vast flow of
information already, actively polling around other subcommunities
is simply not possible for me.

I need to deal with what ends up on the list, I think it would have
been better if you simply posted your S500 driver at the time,
no matter the state. "Release early, release often" and discuss
design on the GPIO mailing list where I can see it, so I have some
idea what is going on here.

It is not too late to take it out if there is some problem from their
side.

When I merge a driver it doesn't mean "definately approved, will
send to Torvalds", type of "seal of approval" it rather usually it
means "I want to test it in linux-next in due time for the merge
window".

I don't mind taking it out if there are problems, and I do not mind
even reverting it in the -rc phase if there are problems.
I don't mind having to revert patches like this or even rebasing
the tree if required.

However if they do not come back at all within some week or
two that is passivity and then it goes in.

Hm how typical :/

Getting to serial is paramount to getting anywhere with the
hacking. I see this becomes a bit of showstopper for your
development work here.

No problem we keep it to one entry.

OK nice!

We can talk to kernel.org about setting up a list, that probably works
quicker.
