[PATCH] fix for Documentation/dvb/bt8xx.txt?=
* /usr/src/linux-2.6.12/Documentation/dvb/bt8xx.txt almost completely remade the text file with the following focuses: useful infos for beginners: how to load modules manually and automatically developers infos are reduced to a minimum as module loading works automatic in kernel >= 2.6.12 by loading modules bttv and dvb-bt8xx I completely erased the out of date TwinHan part dealing with additional parameters, debug parameters, and overriding autodetection Further up to date information about TwinHan + clones can be found in /Documentation/dvb/ci.txt Signed-off-by: Uwe Bugla <uwe.bugla@gmx.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

-How to get the Nebula, PCTV and Twinhan DST cards working
+How to get the Nebula Electronics DigiTV, Pinnacle PCTV Sat, Twinhan DST + clones working
-This class of cards has a bt878a as the PCI interface, and

-Please pay close attention to the warning about the bttv module
-options below for the DST card.
+This class of cards has a bt878a chip as the PCI interface.
+The different card drivers require the bttv driver to provide the means
+to access the i2c bus and the gpio pins of the bt8xx chipset.

In general you need to load the bttv driver, which will handle the gpio and

+For further details about TwinHan DST + clones see /Documentation/dvb/ci.txt.
-3a) Nebula / Pinnacle PCTV
+3a) The manual approach
- $ modprobe bttv (normally bttv is being loaded automatically by kmod)
- $ modprobe dvb-bt8xx (or just place dvb-bt8xx in /etc/modules for automatic loading)
+Loading modules:
+modprobe bttv
+modprobe dvb-bt8xx
+Unloading modules:
+modprobe -r dvb-bt8xx
+modprobe -r bttv
-3b) TwinHan and Clones
+3b) The automatic approach
- $ modprobe bttv i2c_hw=1 card=0x71
- $ modprobe dvb-bt8xx
- $ modprobe dst
-The value 0x71 will override the PCI type detection for dvb-bt8xx,
-which is necessary for TwinHan cards.
-If you're having an older card (blue color circuit) and card=0x71 locks
-your machine, try using 0x68, too. If that does not work, ask on the
-mailing list.
-The DST module takes a couple of useful parameters:
+If not already done by installation, place a line either in
+/etc/modules.conf or in /etc/modprobe.conf containing this text:
+alias char-major-81 bttv
-a. verbose takes values 0 to 5. These values control the verbosity level.
-b. debug takes values 0 and 1. You can either disable or enable debugging.
-c. dst_addons takes values 0 and 0x20:
-- A value of 0 means it is a FTA card.
-- A value of 0x20 means it has a Conditional Access slot.
+Then place a line in /etc/modules containing this text:
-The autodetected values are determined by the "response string"
-of the card, which you can see in your logs:
-e.g.: dst_get_device_id: Recognize [DSTMCI]
+Reboot your system and have fun!
