[PATCHv2 1/9] v4l2: rename V4L2_TUNER_ADC to V4L2_TUNER_SDR

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

 



SDR receiver has ADC (Analog-to-Digital Converter) and SDR transmitter
has DAC (Digital-to-Analog Converter) . Originally I though it could
be good idea to have own type for receiver and transmitter, but now I
feel one common type for SDR is enough. So lets rename it.
