    why does this need to be a separate rate array and cannot live in the general
    pll rate array?

    The plls are general purpose, so we shouldn't limit them arbitarily.

    I currently only see some frequencies (594MHz, 297MHz, 54MHz) that are present
    in both arrays but have different settings. As your patch description says
    that these settings reduce clock jitter, wouldn't the general frequencies also
    profit from merging these new values into the general rate array?


    Heiko
