Subject: [PATCH v5 3/6] arm64: dts: ti: k3-j7200-main.dtsi: Add USB to SERDES lane MUX
Date: Wed, 30 Sep 2020 15:20:29 +0300	[thread overview]
Message-ID: <20200930122032.23481-4-rogerq@ti.com> (raw)
In-Reply-To: <20200930122032.23481-1-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.
