I pushed my sdsprpcd implementation to github, which is responsible for initializing the sensors, and uses this ioctl:
https://github.com/flto/fastrpc
Note: it uses my own WIP fastrpc "library" instead of the one from linaro, I also have other related code, like a sensor client, and cDSP/aDSP compute examples, but need to confirm that I can share them
Also, the corresponding dts patch I sent has a problem, the label = "dsps"; should be label = "sdsp"; (copied the "dsps" from downstream, but upstream expects "sdsp"), will send a v2 later today.
