The vivid driver has been extended to provide CEC adapters for the HDMI input and HDMI outputs in order to test CEC applications. This CEC emulation is faithful to the CEC timings (i.e., it all at a snail's pace).

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.
