Output power level is specified in units of dBuV (as explained at
http://www.linuxtv.org/downloads/v4l-dvb-apis/ch01s09.html#fm-tx-controls).
Shouldn't it be converted to WL1273 specific power level value?
My understanding:
If output power level specified using "V4L2_CID_TUNE_POWER_LEVEL" is 122
(dB/uV), then
power level value to be passed for WL1273 should be '0'.
Please correct me, if I got this conversion wrong.
Thanks and regards,
Pramodh
