Comment # 12 on bug 64503 from Pierre Ossman

So I tried that, and things are now back to ~110 seconds before a glitch. This
is the code in case anyone's curious:

    base_bits = fls(24000);
    clock_bits = fls(clock);

    shift = min(32 - base_bits, 32 - clock_bits);

    WREG32(DCCG_AUDIO_DTO0_PHASE, 24000 << shift);
    WREG32(DCCG_AUDIO_DTO0_MODULE, clock << shift);

So that didn't help...
