Hi Chris, the non-SCMI solution and SCMI solution is different from the clk resource etc. So for current qcom_aoss.com driver, I am expecting the qdss clk resource feature inside this driver may have some different design. More details is discussed via other internal emails as well. Currently, we want to have qcs9100(non-scmi) compatible added to differentiate sa8775p(scmi) compatible firstly to not blocking IOT and AUTO separately. Currently it is a looping dependency for moving forward. Feel free to let us know if you have other opinions. > > >> Signed-off-by: Tengfei Fan <quic_tengfan@quicinc.com> >> --- >> Introduce support for the QCS9100 SoC device tree (DTSI) and the >> QCS9100 RIDE board DTS.

Document the Always-On Subsystem side channel on the QCS9100 Platform. QCS9100 is drived from SA8775p. Currently, both the QCS9100 and SA8775p platform use non-SCMI resource. In the future, the SA8775p platform will move to use SCMI resources and it will have new sa8775p-related device tree. Consequently, introduce "qcom,qcs9100-aoss-qmp" to describe non-SCMI based AOSS channel. Signed-off-by: Tengfei Fan <quic_tengfan@quicinc.com> --- Introduce support for the QCS9100 SoC device tree (DTSI) and the QCS9100 RIDE board DTS. The QCS9100 is a variant of the SA8775p. While the QCS9100 platform is still in the early design stage, the QCS9100 RIDE board is identical to the SA8775p RIDE board, except it mounts the QCS9100 SoC instead of the SA8775p SoC. The QCS9100 SoC DTSI is directly renamed from the SA8775p SoC DTSI, and all the compatible strings will be updated from "SA8775p" to "QCS9100". The QCS9100 device tree patches will be pushed after all the device tree bindings and device driver patches are reviewed.
