mne-python: Units of PSD wrong?

mne.raw.plot_psd labels the PSD with either “uV/sqrt(Hz)” (if dB=False) or “uV/Hz (dB)”. Both seem to be incorrect as they should be “uV**2/Hz” and “dB”, respectively.

I’m fine with leaving it as ASD if linear spectrum is used and PSD if log is used. But if people really need to be able to plot PSD with a linear spectrum, for backward compatibility we could do:

estimate : str
    Can be "power" for power spectral density (PSD), "amplitude" for
    amplitude spectrum density (ASD), or "auto" (default), which uses "power"
    when dB is True and "amplitude" otherwise.
