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

Where is the rest of the changelog? v2?

Where are links to previous versions (or: why aren't you using b4?)?

Best regards,
