Subject: [PATCH 2/6] arm64: dts: k3-am6: Add mux-controller DT node required for muxing SERDES
Date: Wed, 29 May 2019 14:48:08 +0530 [thread overview]
Message-ID: <20190529091812.20764-3-kishon@ti.com> (raw)
In-Reply-To: <20190529091812.20764-1-kishon@ti.com>
Add mux-controller DT node as a child node of scm_conf. This is
required for muxing SERDES between USB, PCIe and ICSS2 SGMII.
