Qualcomm SDM845 SoC features a SLPI DSP which uses FastRPC through an allocated memory region to load files from the host filesystem such as sensor configuration files. Add a FastRPC node at /dev/fastrpc-sdsp and a DMA region, similar to downstream, to allow userspace to communicate with the SLPI via the FastRPC interface for initializing the sensors on the SLPI.
