/*
Definitions for the Philips SAA7196 digital video decoder,
scaler, and clock generator circuit (DESCpro), as used in
the PlanB video input of the Powermac 7x00/8x00 series.
Copyright (C) 1998 Michel Lanners (mlan@cpu.lu)
The register defines are shamelessly copied from the meteor
driver out of NetBSD (with permission),
and are copyrighted (c) 1995 Mark Tinguely and Jim Lowe
(Thanks !)
Additional debugging and coding by Takashi Oe (toe@unlinfo.unl.edu)
The default values used for PlanB are my mistakes.
