+Subject: [PATCH 5005/5006] arm64: dts: allwinner: h616: OrangePi Zero 2: Add
+ USB nodes
+
+The OrangePi Zero 2 has one USB-A host port, VBUS is provided by
+a GPIO controlled regulator.
+The USB-C port is meant to power the board, but is also connected to
+the USB 0 port, which we configure as an MUSB peripheral.
