1 Qualcomm Resource Power Manager (RPM) over SMD
3 This driver is used to interface with the Resource Power Manager (RPM) found in
4 various Qualcomm platforms. The RPM allows each component in the system to vote
5 for state of the system resources, such as clocks, regulators and bus
11 Definition: must be one of:
16 Value type: <stringlist>
17 Definition: Shared Memory channel used for communication with the RPM
21 The RPM exposes resources to its subnodes. The below bindings specify the set
22 of valid subnodes that can operate on these resources.
26 Regulator nodes are identified by their compatible:
31 Definition: must be one of:
32 "qcom,rpm-pm8841-regulators"
33 "qcom,rpm-pm8941-regulators"
43 Usage: optional (pm8841 only)
45 Definition: reference to regulator supplying the input pin, as
46 described in the data sheet

66 The regulator node houses sub-nodes for each regulator within the device. Each
67 sub-node is identified using the node's name, with valid values listed for each
