True, fair enough.. RFC is request for comments. Anyways, that is
besides the point.

Yes please. There would be other dts changes that are probably ready and
I really wont be tracking everything happening on other drivers. If the
binding is present at least in next, it is a good indication of things
clean and ready to go.

I have'nt looked at any conventions, The style I prefer to follow when I do
submissions: It is my job to get the bindings in, until then my actual
dts is just "request for comments". Only after the bindings are merged
do I formally submit dts - simply because I dont expect dts maintainer
to track what happened to my driver's binding and discussions there of.

Seriously, is'nt it really reasonable for dts maintainer to check every
single driver's development status in 15 different mailing lists?
Because, it sounds like what you are asking. At least I wont have time
for it..


I really am curious how Arnd / Tony actually pull this one off.. If they
have continous cron job for checking if your patch is ready... I doubt
it..
