+	select SPI
+	select MDIO
+	help
+	  The ADIN2111 is a low power, 2-port 10BASE-T1L transceiver
+	  designed for industrial Ethernet applications, and is 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 switch,
+	  the ADIN2111 enables direct connectivity with a variety of controllers
+	  via a serial peripheral inter-face (SPI).

+	  ADIN2111 device driver initialization priority.
+	  Must be initialized after SPI, but before MDIO
+	  and ports.
+
+	  Both ports use ETH_INIT_PRIORITY initialization priority.
+

+	  a memory buffer before the Ethernet frame is dropped.
+
+config ETH_ADIN2111_SPI_CFG0
