For the DT, the DSP-related No, it shouldn't be. We should have the ability to build a single kernel image which will run on many systems, including both your system with a DSP and other systems without. > nodes and the LPASS-related nodes shouldn't overlap.

The selection of DSP use sounds like something which isn't part of the description of the hardware but rather a runtime policy decision (at least in so far as non-DSP is ever an option).
