Subject: [PATCH v2 2/5] dt-bindings: interconnect: Add Qualcomm SM6350 NoC support
Date:   Fri, 20 May 2022 09:03:14 +0200
Message-Id: <20220520070318.48521-3-luca.weiss@fairphone.com>

Add bindings for Qualcomm SM6350 Network-On-Chip interconnect devices.

As SM6350 has two pairs of NoCs sharing the same reg, allow this in the
binding documentation, as was done for qcm2290.

Because the main qcom,rpmh.yaml file is getting too complicated for our
use cases, create a new qcom,rpmh-common.yaml and a separate
qcom,sm6350-rpmh.yaml that defines our new bindings.

+description: |
+   RPMh interconnect providers support system bandwidth requirements through
+   RPMh hardware accelerators known as Bus Clock Manager (BCM). The provider is
+   able to communicate with the BCM through the Resource State Coordinator (RSC)
+   associated with each execution environment. Provider nodes must point to at
+   least one RPMh device child node pertaining to their RSC and each provider
+   can map to multiple RPMh resources.
