-Qualcomm RPM/RPMh Power domains
-
-For RPM/RPMh Power domains, we communicate a performance state to RPM/RPMh
-which then translates it into a corresponding voltage on a rail
-
-Required Properties:
- - compatible: Should be one of the following
-	* qcom,msm8976-rpmpd: RPM Power domain for the msm8976 family of SoC
-	* qcom,msm8996-rpmpd: RPM Power domain for the msm8996 family of SoC
-	* qcom,msm8998-rpmpd: RPM Power domain for the msm8998 family of SoC
-	* qcom,qcs404-rpmpd: RPM Power domain for the qcs404 family of SoC
-	* qcom,sdm845-rpmhpd: RPMh Power domain for the sdm845 family of SoC
- - #power-domain-cells: number of cells in Power domain specifier
