From: Leonard Göhrs <l.goehrs@xxxxxxxxxxxxxx>
The Linux Automation GmbH FairyTux2 is a small Linux device based on
an Octavo Systems OSD32MP153c SiP, that occupies just two slots on a
DIN rail.
The device contains an eMMC for storage, a gigabit Ethernet
connection, a CAN bus and a RS485 transceiver.
Add support for the lxa-fairytux2 generation 1 and 2 boards based on
the STM32MP153c.
