Enable the WCNSS (Riva) subsystem on MSM8960-based devices to support Bluetooth and Wi-Fi.
Add the required device tree nodes and resources, including memory regions, clocks, interconnects, and communication interfaces used by the WCNSS firmware and drivers. Changes: - Add Riva (WCNSS) nodes: firmware memory, WCN3660 iris radio, Bluetooth and Wi-Fi subdevices, and pinctrl states - Add SMSM and SPS nodes for coordination with the WCNSS subsystem - Add shared memory and hardware mutex for inter-processor communication - Add SCM node for secure channel manager interaction - Add RPM clock controller and required QDSS clock resource - Add bindings for SPS interrupt controller and RPM clocks Known limitations (not addressed in this series): The wcn36xx driver appears to misclassify 2.4 GHz networks as 5 GHz during hardware scanning, preventing association with 2.4 GHz networks. This issue has also been observed on MSM8916 and MSM8953 platforms using WCN3620 [1][2]. Tested on: - Sony Xperia SP - Samsung Galaxy Express (SGH-I437) - secure firmware loading not yet functional (separate series pending) [1] https://github.com/msm8916-mainline/linux/commit/cc4abc694fcf2c942410136bc58a61e79bf21e83 [2] https://github.com/msm8953-mainline/linux/commit/779c9627ec0b971bf466588e64fe530cf78a414d Signed-off-by: Antony Kurniawan Soemardi <[email protected]> --- Antony Kurniawan Soemardi (10): dt-bindings: clock: qcom,rpmcc: add msm8960 compatible dt-bindings: mfd: syscon: add qcom,msm8960-sps-sic mfd: qcom_rpm: add msm8960 QDSS clock resource clk: qcom: clk-rpm: add msm8960 compatible ARM: dts: qcom: msm8960: add RPM clock controller and fix USB clocks ARM: dts: qcom: msm8960: add SCM ARM: dts: qcom: msm8960: add SMEM & hwmutex ARM: dts: qcom: msm8960: add SMSM & SPS ARM: dts: qcom: msm8960: add Riva ARM: dts: qcom: msm8960: huashan: enable Wi-Fi and Bluetooth .../devicetree/bindings/clock/qcom,rpmcc.yaml | 5 +- Documentation/devicetree/bindings/mfd/syscon.yaml | 2 + .../boot/dts/qcom/qcom-msm8960-sony-huashan.dts | 19 +++ arch/arm/boot/dts/qcom/qcom-msm8960.dtsi | 157 ++++++++++++++++++++- drivers/clk/qcom/clk-rpm.c | 1 + drivers/mfd/qcom_rpm.c | 1 + 6 files changed, 182 insertions(+), 3 deletions(-) --- base-commit: 978e0d8216cae014f10326c9a257890cf98a6398 change-id: 20251226-msm8960-wifi-beecd96c6646 Best regards, -- Antony Kurniawan Soemardi <[email protected]>
