Subject: [PATCH 6/7] arm64: dts: allwinner: h616: OrangePi Zero 2: Add USB nodes
Date: Mon, 12 Sep 2022 00:59:44 +0100 [thread overview]
Message-ID: <20220911235945.6635-7-andre.przywara@arm.com> (raw)
In-Reply-To: <20220911235945.6635-1-andre.przywara@arm.com>
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.
