Hans Verkuil 22e221258b V4L/DVB (12722): v4l2-dev: replace 'kernel number' by 'device node number'.
The term 'kernel number' is very vague, so replace it with the somewhat more
descriptive term 'device node number'.

In one place the local variable 'nr' was used to create the device node number
of the new device name. This has been replaced with the vdev->num field to
more clearly mark this as being the device node number and not the minor
number.

What is it?
===========

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:

	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.

Card Variations:
================

Cards can use either of these two crystals (xtal):
 - 32.11 MHz -> .audio_clock=0x187de7
 - 24.576MHz -> .audio_clock=0x200000
(xtal * .audio_clock = 51539600)

Some details about 30/34/35:

 - saa7130 - low-price chip, doesn't have mute, that is why all those
 cards should have .mute field defined in their tuner structure.

 - saa7134 - usual chip

 - saa7133/35 - saa7135 is probably a marketing decision, since all those
 chips identifies itself as 33 on pci.

saa7134 hardware specs and sample board.


Have fun,
