[PATCH][media] SI2168: Resolve unknown chip version errors with different HVR22x5 models

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



We're seeing a mix of SI2168 demodulators appearing on HVR2205 and
HVR2215 cards, the chips are stamped with different build dates,
verified on my cards.

The si2168 driver detects some cards fine, others not at all. I can
reproduce the working and non-working case. The fix, if we detect a
newer card (D40) load the B firmware.

This fix works well for me and properly enables DVB-T tuning behavior
using tzap.

Thanks to Peter Faulkner-Ball for describing his workaround.
