+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.
