The RPM allows each component in the system + to vote for state of the system resources, such as clocks, regulators and bus + frequencies. + + The SMD or GLINK information for the RPM edge should be filled out. See + qcom,smd.yaml for the required edge properties. All SMD/GLINK related + properties will reside within the RPM node itself. + + The RPM exposes resources to its subnodes. The rpm_requests node must be + present and this subnode may contain children that designate regulator + resources. + + Refer to Documentation/devicetree/bindings/regulator/qcom,smd-rpm-regulator.yaml + for information on the regulator subnodes that can exist under the + rpm_requests. + +maintainers: + - Andy Gross <agross@kernel.org> + - Bjorn Andersson <bjorn.andersson@linaro.org> + +properties: + compatible: + enum: + - qcom,rpm-apq8084 + - qcom,rpm-ipq6018 + - qcom,rpm-ipq9574 + - qcom,rpm-mdm9607 + - qcom,rpm-msm8226 + - qcom,rpm-msm8610 + - qcom,rpm-msm8909 + - qcom,rpm-msm8916 + - qcom,rpm-msm8917 + - qcom,rpm-msm8936 + - qcom,rpm-msm8937 + - qcom,rpm-msm8952 + - qcom,rpm-msm8953 + - qcom,rpm-msm8974 + - qcom,rpm-msm8976 + - qcom,rpm-msm8994 + - qcom,rpm-msm8996 + - qcom,rpm-msm8998 + - qcom,rpm-qcm2290 + - qcom,rpm-qcs404 + - qcom,rpm-sdm660 + - qcom,rpm-sm6115 + - qcom,rpm-sm6125 + - qcom,rpm-sm6375 + + clock-controller: + $ref: /schemas/clock/qcom,rpmcc.yaml# + unevaluatedProperties: false + + power-controller: + $ref: /schemas/power/qcom,rpmpd.yaml# + + qcom,glink-channels: + $ref: /schemas/types.yaml#/definitions/string-array + description: Channel name used for the RPM communication + items: + - const: rpm_requests + + qcom,smd-channels: + $ref: /schemas/types.yaml#/definitions/string-array + description: Channel name used for the RPM communication + items: + - const: rpm_requests + +patternProperties: + "^regulators(-[01])?$": + $ref: /schemas/regulator/qcom,smd-rpm-regulator.yaml# + unevaluatedProperties: false + +if: + properties: + compatible: + contains: + enum: + - qcom,rpm-apq8084 + - qcom,rpm-mdm9607 + - qcom,rpm-msm8226 + - qcom,rpm-msm8610 + - qcom,rpm-msm8909 + - qcom,rpm-msm8916 + - qcom,rpm-msm8917 + - qcom,rpm-msm8936 + - qcom,rpm-msm8937 + - qcom,rpm-msm8952 + - qcom,rpm-msm8953 + - qcom,rpm-msm8974 + - qcom,rpm-msm8976 + - qcom,rpm-msm8994 +then: + properties: + qcom,glink-channels: false + required: + - qcom,smd-channels +else: + properties: + qcom,smd-channels: false + required: + - qcom,glink-channels + +required: + - compatible + +additionalProperties: false + +examples: + - | + #include <dt-bindings/interrupt-controller/arm-gic.h> + #include <dt-bindings/interrupt-controller/irq.h> + + remoteproc { + compatible = "qcom,msm8916-rpm-proc", "qcom,rpm-proc"; + + smd-edge { + interrupts = <GIC_SPI 168 IRQ_TYPE_EDGE_RISING>; + qcom,ipc = <&apcs 8 0>; + qcom,smd-edge = <15>; + + rpm-requests { + compatible = "qcom,rpm-msm8916"; + qcom,smd-channels = "rpm_requests"; + + clock-controller { + compatible = "qcom,rpmcc-msm8916", "qcom,rpmcc"; + #clock-cells = <1>; + clocks = <&xo_board>; + clock-names = "xo"; + }; + + power-controller { + compatible = "qcom,msm8916-rpmpd"; + #power-domain-cells = <1>; + operating-points-v2 = <&rpmpd_opp_table>; + + rpmpd_opp_table: opp-table { + compatible = "operating-points-v2"; + + opp-1 { + opp-level = <1>; + }; + opp-2 { + opp-level = <2>; + }; + }; + }; + }; + }; + }; |
