 | 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. |
