Subject: [PATCH 3/3] arm64: dts: broadcom: bcm2712: Add USB OTG port
Date: Sun,  2 Aug 2026 15:50:54 +0100	[thread overview]
Message-ID: <20260802145109.728793-4-pbrobinson@gmail.com> (raw)
In-Reply-To: <20260802145109.728793-1-pbrobinson@gmail.com>

The Raspberry Pi 5 has a USB2 OTG port wired up to the
Type-C that uses the same IP in earlier generations so
wire this up so it can be used.
