+Marvell AP806 DFX Server
+------------------------
+
+The Marvell AP806 HW block (which is a core component of the Marvell
+Armada 7K and 8K SOCs) has a set of registers called "DFX
+Server". This set of registers contains miscellaneous registers, most
+of them being used for silicon fine-tuning and manufacturing testing,
+and as such are not publicly documented. However, this DFX server
+register range also contains a few documented and useful registers,
+for example for clock control.
+
+This Device Tree binding allows to represent the entire DFX server
+register space as one single DT node.
+
+Required properties:
+- compatible: the first and second values must be:
+	"simple-mfd", "syscon"
+- reg: address and length of following register sets for the DFX
+  server
