Subject: new zoran-0.5.5 driver

LS,
I'm happy to announce a new version of the zoran driver. It's tested
with against the new xawtv-2.41 (which needs a small patch - attached)
The zoran driver now includes updated drivers for both the saa7110,
the saa7111 (untested) and the saa7185 (untested)
New is a commandline parameter 'swapi2c' to use those zoran cards
which inadvertently switched the i2c SDA/SCL lines. So when you're
ZR36120 based card won't budge, you have another option for trying.
Also improved the Makefile interaction with the settings used during
kernel compilation.
The zoran driver is capable of overlaying and grabbing NTSC/PAL/SECAM
videosources and fullblown scaling. It also allows for reading the
first 22 videolines in YUV422/RGB mode, but I haven't the faintest
clue what use that might bring :) It uses the video_decoder API,
allowing it to use 'foreign' video_decoders.
Since the zr36120 chip is not capable of scatter/gather DMA-lists,
it needs a large chunk of DMA-able memory, supplied by the bigphysarea
patch. This requires a kernel patch! the driver isself runs freely
as a module.
As usual the driver(s) are available at:

Met vriendelijke groet,
Pauline Middelink
