    Subject[PATCH 15/15] phy/rockchip: inno-hdmi: Support more pre-pll configuration
    Date
    From: Algea Cao <algea.cao@rock-chips.com>

    Adding the following freq cfg in 8-bit and 10-bit color depth:

    {
    40000000, 65000000, 71000000, 83500000, 85750000,
    88750000, 108000000, 119000000, 162000000
    }

    New freq has been validated by quantumdata 980.

    For some freq which can't be got by only using integer freq div,
    frac freq div is needed, Such as 88.75Mhz 10-bit. But The actual
    freq is different from the target freq, We must try to narrow
    the gap between them. RK322X only support integer freq div.

    The VCO of pre-PLL must be more than 2Ghz, otherwise PLL may be
    unlocked.
