I agree. ADSP is supposed to come up for every or almost every platform,
because it is crucial for USB and charging.

It's true that LPASS macro codec nodes need resources from ADSP, but
still these are resources internal to the SoC. We disable nodes in DTI
which need an external resource. That's not really the case for LPASS.

Best regards,
