![]() With the MC next gen rework, what's left for media_entity_init() is to just initialize the PADs. However, certain devices, like a FLASH led/light doesn't have any input or output PAD. So, there's no reason why calling media_entity_init() would be mandatory. Also, despite its name, what this function actually does is to initialize the PADs data. So, rename it to media_entity_pads_init() in order to reflect that. The media entity actual init happens during entity register, at media_device_register_entity(). We should move init of num_links and num_backlinks to it. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com> |

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.
