1/* BT848 1.24 Driver for Brooktree's Bt848 based cards.
2 The Brooktree BT848 Driver driver is based upon Mark Tinguely and
3 Jim Lowe's driver for the Matrox Meteor PCI card . The
4 Philips SAA 7116 and SAA 7196 are very different chipsets than
5 the BT848. For starters, the BT848 is a one chipset solution and
6 it incorporates a RISC engine to control the DMA transfers --
7 that is it the actual dma process is control by a program which
8 resides in the hosts memory also the register definitions between

211 Roger Hardiman <roger@cs.strath.ac.uk> submitted
212 various fixes to smooth out the microcode and made
213 all modes consistent.
