The frequency generator allows an external complex impedance to be excited with a known frequency. The response signal from the impedance is sampled by the on-board ADC and a discrete Fourier transform (DFT) is processed by an on-chip DSP engine. The DFT algorithm returns a real (R) and imaginary (I) data-word at each output frequency. Changes since V1: Apply list review feedback: Consistently use poll_time_jiffies. Use be|le cpu endian helpers where applicable. Add various comments. Changes since V2: Fix KernelVersion tag in Documentation. Declare ad5933_default_pdata static. Fix typos.
