Subject: [PATCH v2 4/5] dt-bindings: regulators: convert non-smd RPM Regulators bindings to dt-schema
Date: Mon, 17 Oct 2022 12:23:08 +0200 [thread overview]
Message-ID: <20221005-mdm9615-pinctrl-yaml-v2-4-639fe67a04be@linaro.org> (raw)
In-Reply-To: <20221005-mdm9615-pinctrl-yaml-v2-0-639fe67a04be@linaro.org>
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.

+title: QCOM IPC RPM REGULATOR
+
+description:
+ The Qualcomm RPM over IPC regulator is modelled as a subdevice of the RPM.
+
+ Please refer to Documentation/devicetree/bindings/soc/qcom/qcom,ipc-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.
+
+ For pm8058 l0, l1, l2, l3, l4, l5, l6, l7, l8, l9, l10, l11, l12, l13, l14, l15,
