Tony, if you did not have time for review this patch months ago 
or you found it only today - no problem, I understand it. But 
what I need to know is what will happen with board-rx51-* files 
(and when?) You can see that DT does not have definitions of all 
n900 hw parts (plus it is not in last 3.11 kernel!) which means 
that DT is not usable for me and other n900 people. This also 
means that I cannot rewrite my patches for DT and test if they 
working.

I usually stop looking at new code around -rc4 and concentrate
on fixes until -rc1 or so. So there can be easily one month
delays on reviewing stuff depending on where we are with the
current merge window or -rc cycle, sorry if that's annoying.

The .dts files will be separate from the kernel soonish, so
that's not be a show stopper. Just like all the board specific
.config files are separate from the kernel already. Too bad our
.dts changes did not get merged for v3.12 because of conflicts
with other branches, but hey, they should be independent from the
kernel anyways.

Well... I'd say it is still time to merge them. "New hardware support"
is ok after -rc1.

Sure if there's a good reason like "driver foo is already device
tree only and cannot be used for board bar without blah".

The board files will be going away as soon as things are working
with DT. We've been pretty much only applying fixes to them for
quite some time now. For the timeline, the earliest we'll be able
to remove the board-*.c files and platform data is for v3.13

And it would be good to merge n900 dts support for 3.12. Adding 
device tree at the same release as removing board support files in
same release leaves zero room for testing, and practically guarantees
regressions.

Yes we experienced that with omap4 conversion where it caused
some wl12xx regression. So we might want to keep some omap3
board files around until v3.14 if necessary.

Also please take a look at the "[PATCH 0/4] Clean up legacy platform
data handling for omaps for v3.13" patches I posted few days ago,
those should make it easy to have board specific pdata quirks
for DT based booting.

Regards,

Tony
