Hi Jyri,

I was busy on an other work, so, I did not advance on the tda998x.

If you look at the patch series, it contains 3 independant parts:
- dynamic building of the DAIs in the kirkwood audio controller,
- audio CODEC of the tda998x
- DT card based on audio graph

It seems that only the last part raised a problem.
Otherwise, the simple card works fine with the 2 first parts.

I am merging my patches in 4.1-rc1, and, as soon as I get an image on
my screen :), I will resubmit a patch series but about the tda998x
codec only.

Using i2s and s/pdif at the same time with the simple card asks for a
patch as the one I submitted in february 2014 (ASoC: simple-card: DT
fix and multi DAI links extension). As I am using my DT card, I will
not resubmit it. Eventually, the kirkwood patches are not critical.
