+From: Russell King <rmk+kernel@arm.linux.org.uk>
+Date: Sun, 6 Dec 2015 21:52:06 +0000
+Subject: [PATCH] ARM: dts: Add SolidRun Armada 388 Clearfog A1 DT file
+
+Add support for the SolidRun Armada 388 Clearfog A1 board. This board
+has an Armada 388 microsom, dedicated gigabit ethernet, six switched
+gigabit ethernet ports, SFP cage, two Mini-PCIe/mSATA slots, a m.2 SATA
+slot, and a MikroBUS connector to allow MikroBUS modules to be added.
+
+This DT file adds support for all board facilities with the exception
+of full SFP support.
