The provider is16 able to communicate with the BCM through the Resource State Coordinator (RSC)17 associated with each execution environment. Provider nodes must point to at18 least one RPMh device child node pertaining to their RSC and each provider19 can map to multiple RPMh resources.20 21properties:22 compatible:23 enum:24 - qcom,qdu1000-clk-virt25 - qcom,qdu1000-gem-noc26 - qcom,qdu1000-mc-virt27 - qcom,qdu1000-system-noc28 29 '#interconnect-cells': true30 31 reg:32 maxItems: 133 34allOf:35 - $ref: qcom,rpmh-common.yaml#36 - if:37 properties:38 compatible:39 contains:40 enum:41 - qcom,qdu1000-clk-virt42 - qcom,qdu1000-mc-virt43 then:44 properties:45 reg: false46 else:47 required:48 - reg49 50required:51 - compatible52 53unevaluatedProperties: false54 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
