The provider is 16 able to communicate with the BCM through the Resource State Coordinator (RSC) 17 associated with each execution environment. Provider nodes must point to at 18 least one RPMh device child node pertaining to their RSC and each provider 19 can map to multiple RPMh resources. 20 21properties: 22 reg: 23 maxItems: 1 24 25 compatible: 26 enum: 27 - qcom,sc7180-aggre1-noc 28 - qcom,sc7180-aggre2-noc 29 - qcom,sc7180-camnoc-virt 30 - qcom,sc7180-compute-noc 31 - qcom,sc7180-config-noc 32 - qcom,sc7180-dc-noc 33 - qcom,sc7180-gem-noc 34 - qcom,sc7180-ipa-virt 35 - qcom,sc7180-mc-virt 36 - qcom,sc7180-mmss-noc 37 - qcom,sc7180-npu-noc 38 - qcom,sc7180-qup-virt 39 - qcom,sc7180-system-noc 40 - qcom,sdm845-aggre1-noc 41 - qcom,sdm845-aggre2-noc 42 - qcom,sdm845-config-noc 43 - qcom,sdm845-dc-noc 44 - qcom,sdm845-gladiator-noc 45 - qcom,sdm845-mem-noc 46 - qcom,sdm845-mmss-noc 47 - qcom,sdm845-system-noc 48 49 '#interconnect-cells': 50 const: 1 51 52 qcom,bcm-voters: 53 $ref: /schemas/types.yaml#/definitions/phandle-array 54 description: | 55 List of phandles to qcom,bcm-voter nodes that are required by 56 this interconnect to send RPMh commands. 57 58 qcom,bcm-voter-names: 59 $ref: /schemas/types.yaml#/definitions/string-array 60 description: | 61 Names for each of the qcom,bcm-voters specified. 62 63required: 64 - compatible 65 - reg 66 - '#interconnect-cells' 67 - qcom,bcm-voters 68 69additionalProperties: false 70 71examples: 72 - | 73 #include <dt-bindings/interconnect/qcom,sdm845.h> 74 75 mem_noc: interconnect@1380000 { 76 compatible = "qcom,sdm845-mem-noc"; 77 reg = <0x01380000 0x27200>; 78 #interconnect-cells = <1>; 79 qcom,bcm-voters = <&apps_bcm_voter>; 80 }; 81 82 mmss_noc: interconnect@1740000 { 83 compatible = "qcom,sdm845-mmss-noc"; 84 reg = <0x01740000 0x1c1000>; 85 #interconnect-cells = <1>; 86 qcom,bcm-voter-names = "apps", "disp"; 87 qcom,bcm-voters = <&apps_bcm_voter>, <&disp_bcm_voter>; 88 }; 89
