Mauro Carvalho Chehab 32e2eae23f media: docs: move user-facing docs to the admin guide
Most of the driver-specific documentation is meant to help
users of the media subsystem.

Move them to the admin-guide.

It should be noticed, however, that several of those files
are outdated and will require further work in order to make
them useful again.

The saa7134 driver
==================
Author Gerd Hoffmann
This is a v4l2/oss device driver for saa7130/33/34/35 based capture / TV
boards. See http://www.semiconductors.philips.com/pip/saa7134hl for a
description.
Status
------
Almost everything is working. video, sound, tuner, radio, mpeg ts, ...
As with bttv, card-specific tweaks are needed. Check CARDLIST for a
list of known TV cards and saa7134-cards.c for the drivers card
configuration info.
Build
-----
Pick up videodev + v4l2 patches from http://bytesex.org/patches/.
Configure, build, install + boot the new kernel. You'll need at least
these config options:
.. code-block:: none
CONFIG_I2C=m
CONFIG_VIDEO_DEV=m
Type "make" to build the driver now. "make install" installs the
driver. "modprobe saa7134" should load it. Depending on the card you
might have to pass card=<nr> as insmod option, check CARDLIST for
valid choices.
Changes / Fixes
---------------
Please mail me unified diffs ("diff -u") with your changes, and don't
forget to tell me what it changes / which problem it fixes / whatever
it is good for ...
Known Problems
--------------
* The tuner for the flyvideos isn't detected automatically and the
default might not work for you depending on which version you have.
There is a tuner= insmod option to override the driver's default.
