This adds support for the aDSP, cDSP and MPSS Subsystems found in the SM8550 SoC. The aDSP, cDSP and MPSS needs: - smp2p support nodes to get event back from the subsystems - remoteproc nodes with glink-edge subnodes providing all needed resources to start and run the subsystems In addition, the MPSS Subsystem needs a rmtfs_mem dedicated memory zone. Finally the firmwares file paths are added in the MTP board DT. For the MPSS to successfully start the MPSS DSM driver [3] will be needed. This patchset depends on: - bindings changes at [1] - base SM8550 DT at [2] To: Andy Gross <agross@xxxxxxxxxx> To: Bjorn Andersson <andersson@xxxxxxxxxx> To: Konrad Dybcio <konrad.dybcio@xxxxxxxxxxxxxx> To: Rob Herring <robh+dt@xxxxxxxxxx> To: Krzysztof Kozlowski <krzysztof.kozlowski+dt@xxxxxxxxxx> Cc: linux-arm-msm@xxxxxxxxxxxxxxx Cc: devicetree@xxxxxxxxxxxxxxx Cc: linux-kernel@xxxxxxxxxxxxxxx Cc: Abel Vesa <abel.vesa@xxxxxxxxxx> Signed-off-by: Neil Armstrong <neil.armstrong@xxxxxxxxxx> [1] https://lore.kernel.org/all/20221114-narmstrong-sm8550-upstream-remoteproc-v1-0-104c34cb3b91@xxxxxxxxxx/ [2] https://lore.kernel.org/all/20221116103146.2556846-1-abel.vesa@xxxxxxxxxx/ [3] https://lore.kernel.org/all/20221114-narmstrong-sm8550-upstream-mpss_dsm-v1-0-158dc2bb6e96@xxxxxxxxxx/ --- Abel Vesa (1): arm64: dts: qcom: sm8550: Add interconnect path to SCM node Neil Armstrong (2): arm64: dts: qcom: sm8550: add adsp, cdsp & mdss support nodes arm64: dts: qcom: sm8550-mtp: enable adsp, cdsp & mdss arch/arm64/boot/dts/qcom/sm8550-mtp.dts | 18 ++ arch/arm64/boot/dts/qcom/sm8550.dtsi | 338 ++++++++++++++++++++++++++++++++ 2 files changed, 356 insertions(+) --- base-commit: a237afe452d9079aa024e465642b4cde0a04c7ff change-id: 20221115-topic-sm8550-upstream-dts-remoteproc-5285d7018e39 Best regards, -- Neil Armstrong <neil.armstrong@xxxxxxxxxx>
