Kaanapali introduces changes in DSP IOVA layout and CDSP DMA addressing
that differ from previous SoCs. The SID field moves within the physical

Does the driver work at all on this platform without the changes in this
series? If not, then it is not compatible with "qcom,fastrpc" as you
say here.
Thanks for the clarification
No, it doesn't work on kaanapali without this patch series
I have updated the bindings accordingly to allow
either "qcom,kaanapali-fastrpc" for Kaanapali or "qcom,fastrpc"
for older platforms
