Subject: [PATCH v2 3/6] arm64: dts: ti: k3-j7200-main.dtsi: Add USB to SERDES lane MUX
Date: Mon, 7 Sep 2020 17:52:10 +0300 [thread overview]
Message-ID: <20200907145213.30788-4-rogerq@ti.com> (raw)
In-Reply-To: <20200907145213.30788-1-rogerq@ti.com>
The USB controller can be connected to one of the 2 lanes
of SERDES0 using a MUX. Add a MUX controller node for that.
