    clk: at91: utmi: Set the reference clock frequency · e7c83154
    Wenyou Yang authored
    
    By default, it is assumed that the UTMI clock is generated from
    a 12 MHz reference clock (MAINCK). If it's not the case, the FREQ
    field of the SFR_UTMICKTRIM has to be updated to generate the UTMI
    clock in the proper way.
    
    The UTMI clock has a fixed rate of 480 MHz. In fact, there is no
    multiplier we can configure. The multiplier is managed internally,
    depending on the reference clock frequency, to achieve the target
    of 480 MHz.
    
    The patch is cloned from the patch of mailing-list:
