[media] tm6000: rework and fix IR
Browse files Browse the repository at this point in the history 
Hi

This patch didn't kill Stefan's remotes and just for upload my good part of code.
1. Add some code for show IR activity
2. Add filter for IR remotes
3. Split remotes to different types.
4. Fix stop interrupt pipe when isoc pipe started.

When we decide general way of IR I'll add support our remotes.
For our customers I'll made custom temporary patch without this part.

There a few things to do before putting this driver in production:
- IR NEC with tm5600/6000 TV cards
- IR RC5 with tm5600/6000/6010 TV cards
- CodingStyle;
- Fix audio;
- Fix some panic/OOPS conditions.
