Reality check please.  It already is that complicated.  We have IR
kernel drivers today.

The only way to get out of this situation long-term is to get advanced
IR support into the mainline kernel.

It doesn't matter how that actually looks like.  Could be pretty much
like todays lirc drivers.  Could be some input layer extention for
receiving/sending raw IR codes.  Could be something completely different
such as using the tty layer for that.  That has to be discussed and
agreed on.

What *does* matter is being in mainline.  lirc not being in mainline was
*the* major reason for me to use the input layer to handle TV card IR
support.  Having a in-tree driver depending on a out-of-tree subsystem
for IR is a major pain.

It is certainly a good thing to have only *one* way to handle IR
remotes.  But the kernel side of that way *must* be in mainline.
Everything else simply isn't going to fly.

cheers,
  Gerd
