Ed Maste 83d0eed501 lan867xphy: New driver for Microchip LAN8670/1/2 10BASE-T1S PHYs
10BASE-T1S is a Single Pair Ethernet (SPE) standard, intended for
automotive and industrial applications.  It supports a multidrop "mixing
segment" of at least 25m with up to 8 nodes.

This driver currently does not support per-silicon-revision config or
PHY-Level Collision Avoidance (PLCA), but is sufficient for establishing
basic connectivity.

Device details are available in the "Microchip LAN8670/1/2 10BASE-T1S
Ethernet PHY Transceiver Datasheet".
