Subject: V4L control units

What is preferred way implement controls that could have some known unit
or unknown unit? For example for gain controls, I would like to offer
gain in unit of dB (decibel) and also some unknown driver specific unit.
Should I two controls, one for each unit?
Like that
V4L2_CID_RF_TUNER_LNA_GAIN_AUTO
V4L2_CID_RF_TUNER_LNA_GAIN
V4L2_CID_RF_TUNER_LNA_GAIN_dB
regards
Antti
