Yes, dual WSA881x. I tested streaming, however for the dual WSA881x case 
I need specific amixer settings and an extra hack to make it work (seems 
to port config stuff is broken, especially around VISENSE, it tries to 
use it in the wrong direction I think). For a single WSA881x, it can 
work without any extra hack.

The SoC has at least 4 codec drivers to add ("wsa macro", "rx macro", 
"tx macro", "wcd938x"), with what I am doing right now I only need the 
"wsa macro" codec which I've ported over from downstream. For now I am 
only looking at sending patches for the required ADSP changes, but may 
consider doing something with the "wsa macro" driver at some point.
