+properties:
+  otg-rev:
+    description:
+      Tells usb driver the release number of the OTG and EH supplement with
+      which the device and its descriptors are compliant, in binary-coded
+      decimal (i.e. 2.0 is 0200H). This property is used if any real OTG
+      features (HNP/SRP/ADP) is enabled. If ADP is required, otg-rev should be
+      0x0200 or above.
+    $ref: /schemas/types.yaml#/definitions/uint32
+    enum: [0x0100, 0x0120, 0x0130, 0x0200]
+
+  dr_mode:
+    description:
+      Tells Dual-Role USB controllers that we want to work on a particular
+      mode. In case this attribute isn't passed via DT, USB DRD controllers
+      should default to OTG.
+    $ref: /schemas/types.yaml#/definitions/string
+    enum: [host, peripheral, otg]
+
+  hnp-disable:
+    description:
+      Tells OTG controllers we want to disable OTG HNP. Normally HNP is the
+      basic function of real OTG except you want it to be a srp-capable only B
+      device.
+    type: boolean
+
+  srp-disable:
+    description:
+      Tells OTG controllers we want to disable OTG SRP. SRP is optional for OTG
+      device.
+    type: boolean
+
+  adp-disable:
+    description:
+      Tells OTG controllers we want to disable OTG ADP. ADP is optional for OTG
+      device.
+    type: boolean
+
+  usb-role-switch:
+    description:
+      Indicates that the device is capable of assigning the USB data role
+      (USB host or USB device) for a given USB connector, such as Type-C,
+      Type-B(micro). See connector/usb-connector.yaml.
+
+  role-switch-default-mode:
+    description:
+      Indicates if usb-role-switch is enabled, the device default operation
+      mode of controller while usb role is USB_ROLE_NONE.
+    $ref: /schemas/types.yaml#/definitions/string
+    enum: [host, peripheral]
