Subject: [PATCH v6] dt-bindings: regulators: convert non-smd RPM Regulators
bindings to dt-schema
Convert the non-SMD Regulators bindings to dt-schema, the old text based
bindings will be deleted later since the RPM bindings are not yet converted.
Signed-off-by: Neil Armstrong <neil.armstrong@...aro.org>
Reviewed-by: Rob Herring <robh@...nel.org>

This is a second round of bindings & DT fixes for the MDM9615 platform.
This second round focuses on less trivial changes like pinctrl & regulators bindings,
the remaining work will mainly be fixing the qcom,kpss-timer/qcom,msm-timer situation and
add bindings for qcom,lcc-mdm9615, qcom,kpss-gcc & swir,mangoh-iotport-spi.
Dependencies: None

+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.
