Guennadi Liakhovetski 35b23b5226 V4L/DVB (13651): sh_mobile_ceu_camera: document the scaling and cropping algorithm
The sh_mobile_ceu_camera driver implements an advanced algorithm, combining
scaling and cropping on the client and on the host. Due to its complexity the
algorithm deserves separate documentation.

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,
