RPMh Regulators rpmh-regulator devices support PMIC regulator management via the VRM, ARC and XOB RPMh accelerators. The APPS processor communicates with these hardware blocks via an RSC using command packets. The VRM allows changing four parameters for a given regulator: enable state, output voltage, operating mode, and minimum headroom voltage. The ARC allows changing only a single parameter for a given regulator: its operating level. This operating level is fed into CPR which then decides upon a final explicit voltage for the regulator. The XOB allows changing only a single parameter for a given regulator: its enable state. ======================= Required Node Structure ======================= RPMh regulators must be described in two levels of device nodes. The first level describes the interface with RPMh (resource) and must reside within an RPMh device node. The second level describes properties of one regulator framework interface (of potentially many) for the regulator resource. ================================== First Level Nodes - RPMh Interface ================================== - compatible Usage: required Value type: <string> Definition: Must be "qcom,rpmh-vrm-regulator", "qcom,rpmh-arc-regulator" or "qcom,rpmh-xob-regulator" depending upon the hardware type, VRM, ARC or XOB, of the RPMh managed regulator resource. - qcom,resource-name Usage: required Value type: <string> Definition: RPMh resource name which encodes the the specific instance of a given type of regulator (LDO, SMPS, VS, etc) within a particular PMIC found in the system. This name must match to one that is defined by the bootloader. - qcom,regulator-type Usage: required if qcom,supported-modes is specified or if qcom,init-mode is specified in any subnodes Value type: <string> Definition: The physical type of the regulator including the PMIC family. This is used for mode control. Supported values: "pmic4-ldo", "pmic4-hfsmps", "pmic4-ftsmps", "pmic4-bob", "pmic5-ldo", "pmic5-hfsmps", "pmic5-ftsmps", and "pmic5-bob". - qcom,always-wait-for-ack Usage: optional Value type: <empty> Definition: Boolean flag which indicates that the application processor must wait for an ACK or a NACK from RPMh for every request sent for this regulator including those which are for a strictly lower power state. - <regulator-name>-parent-supply Usage: optional Value type: <phandle> Definition: phandle of the parent supply regulator of one of the regulators for this RPMh resource. The property name is defined by the value specified for the regulator-name property. - qcom,supported-modes Usage: optional; VRM regulators only Value type: <prop-encoded-array> Definition: A list of integers specifying the PMIC regulator modes supported by this regulator. Supported values are RPMH_REGULATOR_MODE_* (i.e. 0 to 4).

The first element should always be 0. Elements must be specified in order from lowest to highest. - qcom,send-defaults Usage: optional Value type: <empty> Definition: Boolean flag which indicates that the initial parameter values should be sent to RPMh before consumers make their own requests. If this flag is not specified, then initial parameters values will only be sent after some consumer makes a request. ========================================= Second Level Nodes - Regulator Interfaces ========================================= - regulator-name Usage: required Value type: <string> Definition: Specifies the name for this RPMh regulator. - regulator-min-microvolt Usage: required Value type: <u32> Definition: For VRM resources, this is the minimum supported voltage in microvolts.
