One thing to bear in mind with device tree is that it's all about
defining an ABI - it's supposed to be stable and OS agnostic so it puts
a lot of pressure on to really address quality problems that become
visible in the bindings.  This stuff is much less critical with platform
data, it's relatively easy to change.

It's fairly obvious that it's only you, or at least only you posting
stuff (I know sometimes there are bigger teams behind people) - the
pressure you're under to get something in is very clear.  A big part of
what I'm saying here is that it would be really helpful if could you
slow down a bit, discuss problems more and avoid cutting corners so
much.  This is likely to save you time overall, you'll have a much
higher success rate and you'll get much better feedback if it's clear
what's going on and that there's an interest in understanding the
issues.

If you need to focus on device tree enablement and there are underlying
problems in the subsystems you're looking at perhaps you need to push
back on whoever's asking you to do the work and say you need the domain
experts to pitch in and help you out.

You're not telling us about the problems you see so it's very difficult
for anyone to help you.

For example with this patch the only information you've sent is the
patch and the fact that you're seeing the error you're ignoring going
off on the system you're working with (which I had to ask to find out
about...).  You've not shown the error message or provided any other
hint which would help anyone understand why the error might be occuring
and what a good solution to the problem is.  Ola's guess seems very
likely but nobody's got enough information to confirm that unless
there's been some off-list ST/Linaro communication.

Obviously with the stuff that's device specific you also have to contend
with the fact that you're working on hardware which just isn't all that
widely available and quite possibly has closed datasheets.

This is a two way thing - one of the tools that maintainers have to try
to drive up the quality of the code is to push back on poor quality
submissions and devote less bandwith to sources of those submissions.

It is true that there's a bunch of people who seem to view review as
being just an annoying obstacle to be dealt with with the minimum
possible effort but in practice all that does is make things more
painful for everyone, they do tend to be more noticable because
"applied, thanks" doesn't make for a big thread.
