It's not necessarily terribly complicated to enable this codec: - we could borrow code from the existing code from the cht_bsw_max98090_ti machine driver which relies on the dpcm driver. - the patches developed for Baytrail-Cr will provide support for the 19.2MHz MCLK needed by this codec, they should land on the alsa-devel mailing list this afternoon or early next week. The main issue is to find hardware and someone with bandwidth to do the changes.
