12description: |
13  The ADIN1140 (also called AD3306) is a low power single port
14  10BASE-T1S MAC-PHY. It integrates an Ethernet PHY with a MAC
15  and all the associated analog circuitry.
16  The device tries to implement the Open Alliance TC6 10BASE-T1x MAC-PHY
17  Serial Interface specification and is compliant with the
18  IEEE 802.3cg-2019 Ethernet standard for 10 Mbps single pair
19  Ethernet (SPE). The device has a 4-wire SPI interface for
20  communication between the MAC and host processor.
