Once again: how about agreement about the LIRC interface
(kernel-userspace) and merging the actual LIRC code first? In-kernel
decoding can wait a bit, it doesn't change any kernel-user interface.

I'd like to see a semi-complete design for an in-kernel IR system
before anything is merged from any source.

This is a way to nowhere, there is no logical dependency between LIRC
and input layer IR.

There is only one thing which needs attention before/when merging LIRC:
the LIRC user-kernel interface. In-kernel "IR system" is irrelevant and,
actually, making a correct IR core design without the LIRC merged can be
only harder.

This sounds like "merge first, think later"...

The question is why we need to merge lirc interface right now, before we
agreed on the sybsystem architecture? Noone _in kernel_ user lirc-dev
yet and, looking at the way things are shaping, no drivers will be
_directly_ using it after it is complete. So, even if we merge it right
away, the code will have to be restructured and reworked. Unfortunately,
just merging what Jarod posted, will introduce sysfs hierarchy which
is userspace interface as well (although we not as good maintaining it
at times) and will add more constraints on us.

That is why I think we should go the other way around - introduce the
core which receivers could plug into and decoder framework and once it
is ready register lirc-dev as one of the available decoders.
