+description: |
+  Devicetree bindings for a generic USB charger.
+
+  The node should be either a child of a USB node, or connect to the USB
+  node through the graph. The USB node must have the usb-role-switch property
+  set. The USB charger will report as online when the USB role is set to device,
+  and offline otherwise.
+
+properties:
+  compatible:
+    const: usb-charger
+
+  port: true
+
+required:
+  - compatible
+
+additionalProperties: false
+
+examples:
+  - |+
+    usb_charger: usb-charger {
+      compatible = "usb-charger";
+
+      port {
+        usb_charger_ep: endpoint {
+          remote-endpoint = <&usb_otg>;
+        };
+      };
