The SolidRun Clearfog GT-8K is based on Marvell Armada 8040 SoC.

  https://wiki.solid-run.com/doku.php?id=products:a8040:clearfoggt8k

The following devices were tested with this DT on top of kernel
v4.19-rc4:

  * 1GB Ethernet WAN

  * 4 ports 1GB Ethernet switch (2.5GB uplink)

  * SFP port

  * SATA on CON3 PCIe slot

  * USB3 type A port

  * SD card and eMMC

  * 2 LEDs

  * 2 push buttons
