    ARM: davinci: dm644x: fix out range signal for ED · e37212aa
    Lad, Prabhakar authored
    Fix the video clock setting when custom timings are used with
    pclock <= 27MHz. Existing video clock selection uses PLL2 mode
    which results in a 54MHz clock whereas using the MXI mode results
    in a 27MHz clock (which is the one actually desired).
    
    This bug affects the Enhanced Definition (ED) support on DM644x.
    Without this patch, out-range signals errors are were observed on
    the TV when viewing ED. An out-of-range signal is often caused when
    the field rate is above the rate that the television will handle.
