Please look into that, maybe set up a reply-to or something. Anyway, thanks for your responses -- that clears a lot up. I recommend to also create your own tda18271 config structure, as I have a pending pull request that will tweak the tda18271 configuration within that hcw_tda18271_config structure -- Id hate for your board to break as a result of using somebody else's config. About the SAA7131 - correct -- it is a SAA713x combined with a TDA8295 analog IF demod. I was just checking to see that it was actually what your board uses. Looks good to me. As far as the analog input setup, have you verified that those work properly, or did you also copy those from the HVR1120 configuration? If you havent verified those yourself, I recommend removing them from your patch -- better to not check in untested configurations, as it may lead others to believe that it should work, causing support problems for the future. After you re-submit with the above recommended changes, I'll be happy to push the patch for you.
