PCI glue logic for multimedia MJPEG, MPEG1 & DVD.
Paired with every single TV standard for video capture in the fairly decent number of subvendor
iterations.

ZR36057 is known to have two HW quirks that are been fixed with ZR36067.

- Stub, eventually decouple AV PCI controller part from the actual client cards;

Known mix-ins:
- s3virge.cpp uses SAA7110 for Scenic Highway overlay available with its S3 LPB connector;
- apple/pippin.cpp uses bt856, reused by LML33 as TV encoder;
- jaleco/tetrisp2.cpp stepstag uses adv7176;
