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 completes support for the SLPI in the Qualcomm SDM845 SoC by adding the SLPI to the SDM845 DTS and enable it for 2 hardware devices: - Oneplus 6 - SHIFTPHONES SHIFT6mq * Related patches * 1. Remoteproc changes to support the SLPI DSP in SDM845 (v2): https://lore.kernel.org/linux-remoteproc/20230327183736.496170-1-me@dylanvanassche.be/ 2. FastRPC changes to support the SLPI DSP in SDM845 (v2): https://lore.kernel.org/linux-arm-msm/20230327184204.498032-1-me@dylanvanassche.be/ This serie does not depend on any serie, but all of them are necessary to enable the feature in the end. * Changelog * Changes in v2: - Removed double blank lines - Enforce alphabetically order for 'slpi_pas' - Reordered 'slpi_pas' properties - Fixed FastRPC syntax - Dropped qcom,assign-all-mem property as this is not necessary anymore Kind regards, Dylan Van Assche Dylan Van Assche (5): dts: arm64: qcom: sdm845: add SLPI remoteproc dt-bindings: misc: qcom,fastrpc: allow FastRPC node without reg entry dts: arm64: qcom: sdm845: add SLPI FastRPC support dts: arm64: qcom: sdm845-oneplus: enable SLPI dts: arm64: qcom: sdm845-shift-axolotl: enable SLPI .../bindings/misc/qcom,fastrpc.yaml | 3 +- .../boot/dts/qcom/sdm845-oneplus-common.dtsi | 5 ++ .../boot/dts/qcom/sdm845-shift-axolotl.dts | 5 ++ arch/arm64/boot/dts/qcom/sdm845.dtsi | 59 +++++++++++++++++++ 4 files changed, 70 insertions(+), 2 deletions(-)
