Sorry I should have been clearer. The dynamic debug allows you to enbale
debug logs without recompiling

So after boot:
echo -n 'module snd_soc_sst_mfld_platform +p' > /sys/kernel/debug/dynamic_debug/control

this will enable prints, so when you start audio, the firmware would be
downloaded, and please grab the dmesg ouput and send...

So this makes me suspect interrupts, we should have seen something here

Liam, do you know how whats different in BYT devices from interrupts. I
recall Jarkko saying some issues with the way interrupts are exposed..?
