Subject[PATCH v3 1/7] dt-bindings: power: Add qcom rpm power domain driver bindings
Date
Add DT bindings to describe the rpm power domains found on Qualcomm
Technologies, Inc. SoCs. These power domains communicate a performance
state to RPM, which then translates it into corresponding voltage on a
PMIC rail.

+Qualcomm RPM Power domains
+
+For RPM Power domains, we communicate a performance state to RPM
+which then translates it into a corresponding voltage on a rail
+
+Required Properties:
+ - compatible: Should be one of the following
+ * qcom,msm8996-rpmpd: RPM Power domain for the msm8996 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/qcom-opp.txt for more details
+
+Example:
+
+ rpmpd: power-controller {
+ compatible = "qcom,msm8996-rpmpd";
+ #power-domain-cells = <1>;
+ operating-points-v2 = <&rpmpd_opp_table>;
+ };
+
+ rpmpd_opp_table: opp-table {
+ compatible = "operating-points-v2-qcom-level";
+
+ rpmpd_opp1: opp1 {
+ qcom,level = <1>;
+ };
+
+ rpmpd_opp2: opp2 {
+ qcom,level = <2>;
+ };
+
+ rpmpd_opp3: opp3 {
+ qcom,level = <3>;
+ };
+
+ rpmpd_opp4: opp4 {
+ qcom,level = <4>;
+ };
+
+ rpmpd_opp5: opp5 {
+ qcom,level = <5>;
+ };
+
+ rpmpd_opp6: opp6 {
+ qcom,level = <6>;
+ };
+ };
