Thanks a lot for testing! I also tested concurrent playback with the
primary and the secondary DAI (on Exynos4412), enabling the secondary DAI
with a bit hackish patch as in this branch:
git://linuxtv.org/snawrocki/samsung.git sound/odroidx2-simple-card-v2
I'm planning to do necessary changes to enable the secondary DAI properly
with simple-card, once we're done with this series.
