Hi Our TV card Behold X7 has two different RF input. This RF inputs can switch between different RF sources. ANT 1 for analog and digital TV ANT 2 for FM radio The switch controlled by zl10353. How to I can control this switch? I found 2 way 1. Use tuner callback to saa1734. add some params like XC5000_TUNER_SET/XC5000_TUNER_SET_TV to the xc5000.h call tuner callback from xc5000_set_analog_params with new params about switching. In this case inside saa7134 need know about zl10353 and configuration. I don't understand how to do. The structure saa7134_dev hasn't pointer to the structure dvb_frontend. Or use hardcoded i2c_addr and params. 2. Direct call switch the switcher from the tuner code. In this case need know TV card type. I think it is not so good idea. With my best regards, Dmitry. -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
