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 lock 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 This series supersedes the earlier dt-bindings-only submission [1] and includes the corresponding driver and DT integration changes. This patch series depends on: [2] "dt-bindings: usb: ci-hdrc-usb2: allow up to 3 clocks for qcom,ci-hdrc" for fixing the USB controller clock configuration on MSM8960. Tested on: - Sony Xperia SP - Samsung Galaxy Express (SGH-I437) - requires additional work for firmware loading (separate series pending) 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 [3][4].
