Hi,

Doing a generic reply on an old post, there's been many about DT though:

I'm actually not excited about more discussion. There was a _ton_ of
it in Edinburgh, with many decisions done. Unless people have gone off
to actually try to implement some of the things we agreed need to be
implemented, and now need to come back with "it didn't work, we need
to change everything", then we shouldn't have to meet and spend
another mind-numbing day discussing DT. Or do we?

Hm. Do we need to meet in a room to talk about that, or can we discuss
it over email?

I would say that they have improved, in particular because we've
started seeing more DT changes go in (and more bindings). There are
some areas that are still difficult, and I think the answer for those
is to find the right people and sit down and hash it out. ELC is
probably a good venue for some of that, but doing it in a room full of
ARM kernel maintainers might not be.

Do you have a proposal and a process in mind? Having something
specific to start a discussion off of is more useful than opening it
up for round table talks.
