Add Epoch Subsystem (EPSS) L3 scaling support on Qualcomm Shikra SoC. EPSS hardware on Shikra is similar to other SoCs but supports only twelve L3 frequency entries (LUT). Reading the LUT beyond supported frequencies can expose incorrect frequencies. Introduce new compatible to represent this constrained variant of EPSS. * icc-shikra dt-bindings: interconnect: qcom,osm-l3: Add EPSS L3 DT binding for Qualcomm Shikra SoC interconnect: qcom: Add EPSS L3 scaling support for Shikra SoC Link: https://patch.msgid.link/20260603-shikra_epss_l3-v3-0-3c2e0b796e78@oss.qualcomm.com Signed-off-by: Georgi Djakov <djakov@kernel.org>
Use a flexible array member to reduce allocation by 1. Add __counted_by for extra runtime analysis. Move counting variable assignment after allocation before any array access.

Add driver for the Qualcomm interconnect buses found in Maili based platforms. The topology consists of several NoCs that are controlled by a remote processor that collects the aggregated bandwidth for each master-slave pairs.

Add Epoch Subsystem (EPSS) L3 interconnect provider support on Qualcomm Shikra SoC. The EPSS L3 block on Shikra SoC is similar to existing Qualcomm EPSS/OSM L3 providers, but supports only up to 12 frequency lookup table entries. Reading beyond the supported LUT entries can expose incorrect frequencies. Add shikra-specific EPSS descriptor shikra_epss_l3_perf_state that reuses existing EPSS configuration with appropriate LUT entries limit.

This series enables QoS configuration for QNOC type device which can be found on X1E80100 platform. It enables QoS configuration for master ports with predefined priority and urgency forwarding. This helps in prioritizing the traffic originating from different interconnect masters at NOC (Network On Chip). The system may function normally without this feature. However, enabling QoS helps optimize latency and bandwidth across subsystems like CPU, GPU, and multimedia engines, which becomes important in high-throughput scenarios. This is a feature aimed at performance enhancement to improve system performance under concurrent workloads. * icc-x1e80100 dt-bindings: interconnect: qcom,x1e80100-rpmh: add clocks property to enable QoS interconnect: qcom: x1e80100: enable QoS configuration Link: https://patch.msgid.link/20260527-x1e80100_qos-v2-0-305c6539e6d2@oss.qualcomm.com Signed-off-by: Georgi Djakov <djakov@kernel.org>
