-Subject: [PATCH] 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.
