According to some tests on the Cubox (Marvell Armada 510 + TDA19988), the S/PDIF input asks for a greater audio clock divider.

I'm not sure these comments are quite right... You start off with adiv at AUDIO_DIV_SERCLK_8, and then you increment it, but the comment says it's AUDIO_DIV_SERCLK_8 ? Shouldn't it become AUDIO_DIV_SERCLK_16 ?
Please review the above change yourself. :)
