Subject: [PATCH v1 2/2] arm64: dts: rockchip: rk3588s: Add USB3 host controller
Date:   Wed, 19 Jul 2023 19:40:15 +0200
Message-Id: <20230719174015.68153-3-sebastian.reichel@collabora.com>

RK3588 has three USB3 controllers. One of them is host-only and uses
the naneng-combphy. The other two are dual-role and using a different
PHY that is not yet supported upstream.
