So right now we have two different approaches to documenting these bindings. Lee
proposed doing it on a per device name, here you are proposing a single file
per type.
What is the prefered approach?
Lee/Lukasz why would you two favour one way or the other?
Device tree maintainers, which is preferred?
Do we assume that any sane person looking up bindings will deploy
grep to find where they are documented, or does it want to more
or less be named after the part (in which case we'll get a lot
of repetition).
Also, the question of whether _'s are acceptable in names
to avoid breaking existing ABI for i2c devices is still open?
I'm assuming that given the current situation and the fact
that the word 'prefered' was used, we are better sticking
with _'s? (that doesn't actually effect this patch, but does
on the next two in this series and I'm being lazy).
