dt-bindings: interconnect: qcom,sa8775p-rpmh: Fix incorrectly added reg and clocks

2025-12-19T08:47:13+00:00

Commit 8a55fbe4c94d ("dt-bindings: interconnect: add reg and clocks properties to enable QoS on sa8775p") claims that all interconnects have clocks and MMIO address space, but that is just not true. Only few have. Bindings should restrict properties and should not allow specifying non-existing hardware description, so fix missing constraints for 'reg' and 'clocks'.

dt-bindings: interconnect: qcom,sm6350-rpmh: Add clocks for QoS

2025-11-19T14:03:00+00:00

Add the clocks for some interconnects to the bindings that are required to set up the QoS correctly. Update one of the examples to aggre2_noc to have an example with clocks. Also while we're at it, remove #interconnect-cells: true as that's already provided from qcom,rpmh-common.yaml.

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

2025-10-31T00:35:22+00:00

Add 'reg' and 'clocks' properties to enable QoS configuration. These properties enable access to QoS registers and necessary clocks for configuration. QoS configuration is essential for ensuring that latency sensitive components such as CPUs and multimedia engines receive prioritized access to memory and interconnect resources. This helps to manage bandwidth and latency across subsystems, improving system responsiveness and performance in concurrent workloads. Both 'reg' and 'clocks' properties are optional. If either is missing, QoS configuration will be skipped. This behavior is controlled by the 'qos_requires_clocks' flag in the driver, which ensures that QoS configuration is bypassed when required clocks are not defined.
