Yes. This indeed seems to be a very good idea.

Ok. As you said you'll do some work at the patches, could you please send us v3
in order to add it into drivers/staging? 

In the case of the API header file, I would tag at the header file that the API
is experimental, so can be changed without prior announcements, etc (in order to
avoid people to use and rely on it it outside lirc). IMO, the better is to keep
such announcement there while we're still working at the hybrid approach, as we
may need to change something during the development phase.

Dmitry,

While lirc is basically a series of input drivers, considering that they have 
lots
in common with the input drivers at V4L/DVB and that we'll need to work on
some glue to merge both, do you mind if I add the lirc drivers at 
drivers/staging from
my trees? 

Cheers,
Mauro.
