Hmmm. Let me see how the protoype turns out keeping that design objective in mind. I've already got the current RC-5 and NEC decoding state machines in cx23885-input a bit layered, but they are taking advantage of specific events signaled by my v4l2_subdev implementation.
Strictly speaking the state machines don't have to. All of the remote protocols I have played with make framing pretty easy.

Hmm. That's not what I just thought I read from Dmitry....
Oh well. If I don'y get it done by 24 Dec, it'll be in the new year.
