-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,sc7180-rpmhpd: RPMh Power domain for the sc7180 family of SoC
- * qcom,sdm845-rpmhpd: RPMh Power domain for the sdm845 family of SoC
- * qcom,sm8150-rpmhpd: RPMh Power domain for the sm8150 family of SoC
- - #power-domain-cells: number of cells in Power domain specifier
- must be 1.
- - operating-points-v2: Phandle to the OPP table for the Power domain.
- Refer to Documentation/devicetree/bindings/power/power_domain.txt
- and Documentation/devicetree/bindings/opp/opp.txt for more details
-
-Refer to <dt-bindings/power/qcom-rpmpd.h> for the level values for
-various OPPs for different platforms as well as Power domain indexes
-
-Example: rpmh power domain controller and OPP table
-
-#include <dt-bindings/power/qcom-rpmhpd.h>
-
-opp-level values specified in the OPP tables for RPMh power domains
-should use the RPMH_REGULATOR_LEVEL_* constants from
-<dt-bindings/power/qcom-rpmhpd.h>
