Subject: [PATCH v2 15/16] arm64: dts: mediatek: mt8195-cherry: Add USB type-A connector
Date: Wed, 10 Jun 2026 16:40:49 +0800	[thread overview]
Message-ID: <20260610084053.2059858-16-wenst@chromium.org> (raw)
In-Reply-To: <20260610084053.2059858-1-wenst@chromium.org>

The MT8195 Cherry design features a USB type-A connector for external
devices.

Add a proper representation for it with a node for the connector and
OF graph connection to the USB hub behind it.
