 I need a test case for it first.  Feel free to send in a

Sadly I have not yet achieved FE_HAS_SIGNAL (TDA10048 reg 1A: FREQ_LOCK)
with _any_ code, though I /have/ had FE_HAS_CARRIER,
FE_HAS_SYNC & FE_HAS_VITERBI.
Hence do not get FE_HAS_LOCK (TDA10048 reg 1A: FEL)
Possibly need to get a spectrum analyser onto the IFOUT pins
to see why the 10048 is not achieving proper lock.

May be a 10048 setup mismatch ...

On that basis I am not willing to submit patches, until I have
demonstrably working tuning !

PS. One of the RF techies said that silicon tuners were _much_
harder work than "can" tuners, hence the increase in s/w needed
to work them ...
