+description: |
+  The ADIN1140 (also called AD3306) is a low power single port
+  10BASE-T1S MAC-PHY. It integrates an Ethernet PHY with a MAC
+  and all the associated analog circuitry.
+  The device implements the Open Alliance TC6 10BASE-T1x MAC-PHY
+  Serial Interface specification and is compliant with the
+  IEEE 802.3cg-2019 Ethernet standard for 10 Mbps single pair
+  Ethernet (SPE). The device has a 4-wire SPI interface for
+  communication between the MAC and host processor.
