No, but we have patches for all of them. > Because the user has the ability to load cx8800 without cx88-dvb, and > likewise, the user has the ability to load cx88-dvb without cx8800, the > attach call must be fully qualified such that the other side of the > driver is not required to be loaded in order for the tuner to work. If you take a look at the code, you'll see that all code is at cx88xx. This module is loaded by cx8800, if you're using analog, or by cx8802, if you're using cx88-dvb or cx88-blackbird. The code initializes xc3028 before tuner attach. > In the case of FusionHDTV5 pci nano, there will never be an attach call > from the analog side of the driver, since the tuner is hidden behind the > s5h1409's i2c gate, and analog mode is not supported with the current > driver.

This will allow i2c_scan to work and both analog and digital modes will work. Btw, this somewhat similar to what dvico_fusionhdtv_hybrid_init() does on cx88-cards. I've added a patch that should open the bridge for s5h1409.

It would be really nice to avoid having to attach it later, on cx88-dvb, although the double attach won't hurt. I'm not sure on how you want to avoid this.
