* @count: number of scan results requested. There are special meanings
* in some chip revisions:
* AR92xx: highest bit set (>=128) for endless mode
* (spectral scan won't stopped until explicitly disabled)
* AR9300 and newer: 0 for endless mode
* @endless: true if endless mode is intended. Otherwise, count value is
* corrected to the next possible value.
* @period: time duration between successive spectral scan entry points
* (period*256*Tclk). Tclk = ath_common->clockrate
* @fft_period: PHY passes FFT frames to MAC every (fft_period+1)*4uS
*
* Note: Tclk = 40MHz or 44MHz depending upon operating mode.
* Typically it's 44MHz in 2/5GHz on later chips, but there's
* a "fast clock" check for this in 5GHz.
