+Marvell Kirkwood SoC Family Device Tree Bindings
+------------------------------------------------
+
+Boards with a SoC of the Marvell Kirkwook family, eg 88f6281
+
+* Required root node properties:
+compatible: must contain "marvell,kirkwood"
+
+In addition, the above compatible shall be extended with the specific
+SoC. Currently known SoC compatibles are:
+
+"marvell,kirkwood-88f6192"
