Subject: [PATCH 2/7] arm64: dts: mediatek: mt8195: add ssusb support
Date:   Tue, 26 Apr 2022 15:41:00 +0200
Message-Id: <20220426134106.242353-3-fparent@baylibre.com>

Add SSUSB support for MT8195. In order to not break any boards, this
commit also enable SSUSB for every board that has xhci0 enabled. The
boards are configured as host-only, in order to not change the current
behavior of the interface.
