[PATCH v2 0/3] Enable QoS configuration on SA8775P
Posted by Odelu Kukatla 4 months, 1 week ago
This series enables QoS configuration for QNOC type device which
can be found on SA8775P 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 since v1:
  - Updated 'reg' and 'clocks' properties as optional.
  - Removed leading zeros in devicetree change.
  - Updated commit message for binding change with justification.

  dt-bindings: interconnect: add reg and clocks properties to enable QoS
    on sa8775p
  interconnect: qcom: sa8775p: enable QoS configuration

Applied, thanks!
