Add DT bindings to describe the rpmh powerdomains found on Qualcomm
Technologies, Inc. SoCs. These power domains communicate a performance
state to RPMh, which then translates it into corresponding voltage on
a PMIC rail.

+Qualcomm RPMh Power domains
+
+For RPMh Power domains, we communicate a performance state to RPMh
+which then translates it into a corresponding voltage on a rail
+
+Required Properties:
+ - compatible: Should be one of the following
+ * qcom,sdm845-rpmhpd: RPMh Power domain for the sdm845 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:
+
+ rpmhpd: power-controller {
+ compatible = "qcom,sdm845-rpmhpd";
+ #power-domain-cells = <1>;
+ operating-points-v2 = <&rpmhpd_opp_table>;
+ };
+
+ rpmhpd_opp_table: opp-table {
+ compatible = "operating-points-v2-qcom-level";
+
+ rpmhpd_opp_ret: opp1 {
+ qcom-level = <16>;
+ };
+
+ rpmhpd_opp_min_svs: opp2 {
+ qcom-level = <48>;
+ };
+
+ rpmhpd_opp_low_svs: opp3 {
+ qcom-level = <64>;
+ };
+
+ rpmhpd_opp_svs: opp4 {
+ qcom-level = <128>;
+ };
+
+ rpmhpd_opp_svs_l1: opp5 {
+ qcom-level = <192>;
+ };
+
+ rpmhpd_opp_nom: opp6 {
+ qcom-level = <256>;
+ };
+
+ rpmhpd_opp_nom_l1: opp7 {
+ qcom-level = <320>;
+ };
+
+ rpmhpd_opp_nom_l2: opp8 {
+ qcom-level = <336>;
+ };
+
+ rpmhpd_opp_turbo: opp9 {
+ qcom-level = <384>;
+ };
+
+ rpmhpd_opp_turbo_l1: opp10 {
+ qcom-level = <416>;
+ };
+ };
