----------------------------------------------------
3
+
4
+
Boards using a SoC of the Marvell Armada 8KP families must carry
5
+
the following root node property:
6
+
7
+
- compatible, with one of the following values:
8
+
9
+
- "marvell,armada-8080", "marvell,armada-ap810-octa", "marvell,armada-ap810"
10
+
when the SoC being used is the Armada 8080
11
+
12
+
Example:
13
+
14
+
compatible = "marvell,armada-8080-db", "marvell,armada-8080",
15
+
"marvell,armada-ap810-octa", "marvell,armada-ap810"
