[PATCH net-next v3 12/12] dt-bindings: net: add Microchip's LAN865X 10BASE-T1S MACPHY

[Parthiban Veerasooran <Parthiban.Veerasooran@microchip.com>]

The LAN8650/1 combines a Media Access Controller (MAC) and an Ethernet
PHY to enable 10BASE-T1S networks. The Ethernet Media Access Controller
(MAC) module implements a 10 Mbps half duplex Ethernet MAC, compatible
with the IEEE 802.3 standard and a 10BASE-T1S physical layer transceiver
integrated into the LAN8650/1. The communication between the Host and the
MAC-PHY is specified in the OPEN Alliance 10BASE-T1x MACPHY Serial
Interface (TC6).
