title: Qualcomm RPM regulator
|
|
|
|
description:
|
|
The Qualcomm RPM regulator is modelled as a subdevice of the RPM.
|
|
|
|
Please refer to Documentation/devicetree/bindings/soc/qcom/qcom,rpm.yaml
|
|
for information regarding the RPM node.
|
|
|
|
The regulator node houses sub-nodes for each regulator within the device.
|
|
Each sub-node is identified using the node's name, with valid values listed
|
|
for each of the pmics below.
