[PATCH v3 0/3] Enable QoS configuration on QCS615

From: Odelu Kukatla

Date: Wed Mar 11 2026 - 06:45:10 EST


This series enables QoS configuration for QNOC type device which
can be found on QCS615 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.

Changes in v3:
- Refactored the schema to define 'clocks' in the top-level
properties block as suggested by Krzysztof Kozlowski.
- Removed the conditional logic that strictly checked for
'qcom,qcs615-aggre1-noc' to define 'clocks'. Instead, the property
is now defined globally but explicitly forbidden for all other
interconnect nodes except aggre1-noc node.

Odelu Kukatla (3):
dt-bindings: interconnect: qcom,qcs615-rpmh: add clocks property to
enable QoS
interconnect: qcom: qcs615: enable QoS configuration
arm64: dts: qcom: talos: Add clocks for QoS configuration
