+	  The LAN865X is a low power, 10BASE-T1S transceiver compliant with
+	  the IEEE® 802.3cg-2019™ Ethernet standard for long reach, 10
+	  Mbps single pair Ethernet (SPE).
+
+	  Featuring an integrated media access control (MAC) and a PHY,
+	  the LAN865X enables direct connectivity with a variety of controllers
+	  via a serial peripheral inter-face (SPI).
