While sensors are connected to GPIOs of the SoC, they cannot be used because the hypervisor blocks direct access to the sensors, thus the DSP must be used to access any sensor on this SoC. The SLPI DSP uses a GLink edge (dsps) to communicate with the host and has a FastRPC interface to load files from the host filesystem such as sensor configuration files. The FastRPC interface does not use regular FastRPC Compute Banks but instead uses an allocated CMA region through which communication happens. * Changes * This patchseries adds support for this remoteproc in the q6v5_pas driver to allow booting the SLPI on the SDM845 and expose its service 400 over QRTR. * Related patches * Support for the FastRPC side of the SLPI and DTS changes are submitted in separate series.
