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 compatible: 23 enum: 24 - qcom,qdu1000-clk-virt 25 - qcom,qdu1000-gem-noc 26 - qcom,qdu1000-mc-virt 27 - qcom,qdu1000-system-noc 28 29 '#interconnect-cells': true 30 31 reg: 32 maxItems: 1 33 34allOf: 35 - $ref: qcom,rpmh-common.yaml# 36 - if: 37 properties: 38 compatible: 39 contains: 40 enum: 41 - qcom,qdu1000-clk-virt 42 - qcom,qdu1000-mc-virt 43 then: 44 properties: 45 reg: false 46 else: 47 required: 48 - reg 49 50required: 51 - compatible 52 53unevaluatedProperties: false 54 55examples: 56 - | 57 #include <dt-bindings/interconnect/qcom,qdu1000-rpmh.h> 58 59 system_noc: interconnect@1640000 { 60 compatible = "qcom,qdu1000-system-noc"; 61 reg = <0x1640000 0x45080>; 62 #interconnect-cells = <2>; 63 qcom,bcm-voters = <&apps_bcm_voter>; 64 }; 65 66 clk_virt: interconnect-0 { 67 compatible = "qcom,qdu1000-clk-virt"; 68 #interconnect-cells = <2>; 69 qcom,bcm-voters = <&apps_bcm_voter>; 70 }; 71
