[patch] v4l: bttv driver update
From: Gerd Knorr
Date: Tue Oct 07 2003 - 05:48:15 EST
Hi,
This patch updates the bttv driver. It depends on the videobuf patch.
Changes:
* usual tv card list updates.
* sysfs adaptions.
* new, experimental i2c adapter code for bt878 chips
(not used by default yet).
* various minor fixes.
Please apply,
Gerd
