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,sc7280-aggre1-noc 41 - qcom,sc7280-aggre2-noc 42 - qcom,sc7280-clk-virt 43 - qcom,sc7280-cnoc2 44 - qcom,sc7280-cnoc3 45 - qcom,sc7280-dc-noc 46 - qcom,sc7280-gem-noc 47 - qcom,sc7280-lpass-ag-noc 48 - qcom,sc7280-mc-virt 49 - qcom,sc7280-mmss-noc 50 - qcom,sc7280-nsp-noc 51 - qcom,sc7280-system-noc 52 - qcom,sc8180x-aggre1-noc 53 - qcom,sc8180x-aggre2-noc 54 - qcom,sc8180x-camnoc-virt 55 - qcom,sc8180x-compute-noc 56 - qcom,sc8180x-config-noc 57 - qcom,sc8180x-dc-noc 58 - qcom,sc8180x-gem-noc 59 - qcom,sc8180x-ipa-virt 60 - qcom,sc8180x-mc-virt 61 - qcom,sc8180x-mmss-noc 62 - qcom,sc8180x-system-noc 63 - qcom,sdm845-aggre1-noc 64 - qcom,sdm845-aggre2-noc 65 - qcom,sdm845-config-noc 66 - qcom,sdm845-dc-noc 67 - qcom,sdm845-gladiator-noc 68 - qcom,sdm845-mem-noc 69 - qcom,sdm845-mmss-noc 70 - qcom,sdm845-system-noc 71 - qcom,sdx55-ipa-virt 72 - qcom,sdx55-mc-virt 73 - qcom,sdx55-mem-noc 74 - qcom,sdx55-system-noc 75 - qcom,sdx65-mc-virt 76 - qcom,sdx65-mem-noc 77 - qcom,sdx65-system-noc 78 - qcom,sm8150-aggre1-noc 79 - qcom,sm8150-aggre2-noc 80 - qcom,sm8150-camnoc-noc 81 - qcom,sm8150-compute-noc 82 - qcom,sm8150-config-noc 83 - qcom,sm8150-dc-noc 84 - qcom,sm8150-gem-noc 85 - qcom,sm8150-ipa-virt 86 - qcom,sm8150-mc-virt 87 - qcom,sm8150-mmss-noc 88 - qcom,sm8150-system-noc 89 - qcom,sm8250-aggre1-noc 90 - qcom,sm8250-aggre2-noc 91 - qcom,sm8250-compute-noc 92 - qcom,sm8250-config-noc 93 - qcom,sm8250-dc-noc 94 - qcom,sm8250-gem-noc 95 - qcom,sm8250-ipa-virt 96 - qcom,sm8250-mc-virt 97 - qcom,sm8250-mmss-noc 98 - qcom,sm8250-npu-noc 99 - qcom,sm8250-system-noc 100 - qcom,sm8350-aggre1-noc 101 - qcom,sm8350-aggre2-noc 102 - qcom,sm8350-config-noc 103 - qcom,sm8350-dc-noc 104 - qcom,sm8350-gem-noc 105 - qcom,sm8350-lpass-ag-noc 106 - qcom,sm8350-mc-virt 107 - qcom,sm8350-mmss-noc 108 - qcom,sm8350-compute-noc 109 - qcom,sm8350-system-noc 110 - qcom,sm8450-aggre1-noc 111 - qcom,sm8450-aggre2-noc 112 - qcom,sm8450-clk-virt 113 - qcom,sm8450-config-noc 114 - qcom,sm8450-gem-noc 115 - qcom,sm8450-lpass-ag-noc 116 - qcom,sm8450-mc-virt 117 - qcom,sm8450-mmss-noc 118 - qcom,sm8450-nsp-noc 119 - qcom,sm8450-pcie-anoc 120 - qcom,sm8450-system-noc 121 122 '#interconnect-cells': 123 enum: [ 1, 2 ] 124 125 qcom,bcm-voters: 126 $ref: /schemas/types.yaml#/definitions/phandle-array 127 items: 128 maxItems: 1 129 description: | 130 List of phandles to qcom,bcm-voter nodes that are required by 131 this interconnect to send RPMh commands. 132 133 qcom,bcm-voter-names: 134 description: | 135 Names for each of the qcom,bcm-voters specified. 136 137required: 138 - compatible 139 - reg 140 - '#interconnect-cells' 141 - qcom,bcm-voters 142 143additionalProperties: false 144 145examples: 146 - | 147 #include <dt-bindings/interconnect/qcom,sdm845.h> 148 149 mem_noc: interconnect@1380000 { 150 compatible = "qcom,sdm845-mem-noc"; 151 reg = <0x01380000 0x27200>; 152 #interconnect-cells = <1>; 153 qcom,bcm-voters = <&apps_bcm_voter>; 154 }; 155 156 mmss_noc: interconnect@1740000 { 157 compatible = "qcom,sdm845-mmss-noc"; 158 reg = <0x01740000 0x1c1000>; 159 #interconnect-cells = <1>; 160 qcom,bcm-voter-names = "apps", "disp"; 161 qcom,bcm-voters = <&apps_bcm_voter>, <&disp_bcm_voter>; 162 }; 163
