 Atmel AT91 device tree bindings.
 ================================
 
+Boards with a SoC of the Atmel AT91 or SMART family shall have the following
+properties:
+
+Required root node properties:
+compatible: must be one of:
+ * "atmel,rm9200"
+ * "atmel,at91sam9260"
+ * "atmel,at91sam9261"
+ * "atmel,at91sam9263"
+ * "atmel,at91sam9x5" for the x5 family, shall be extended with the specific SoC
+   compatible:
+    o "atmel,at91sam9g15"
+    o "atmel,at91sam9g25"
+    o "atmel,at91sam9g35"
+    o "atmel,at91sam9x25"
+    o "atmel,at91sam9x35"
+ * "atmel,at91sam9g20"
+ * "atmel,at91sam9g45"
+ * "atmel,at91sam9n12"
+ * "atmel,at91sam9rl"
+ * "atmel,sama5" for the cortexA5 family, shall be extended with the specific
+   SoC family:
+    o "atmel,sama5d3" shal be exteneded with the specific SoC compatible:
+       - "atmel,samad31"
+       - "atmel,samad33"
+       - "atmel,samad34"
+       - "atmel,samad35"
+       - "atmel,samad36"
+    o "atmel,sama5d4"
+
+
+In addition, the above compatible shall be extended with the specific
+SoC and board used. Currently known SoC compatibles are:
+    "marvell,berlin2"      for Marvell Armada 1500 (BG2, 88DE3100),
+    "marvell,berlin2cd"    for Marvell Armada 1500-mini (BG2CD, 88DE3005)
+    "marvell,berlin2ct"    for Marvell Armada ? (BG2CT, 88DE????)
+    "marvell,berlin2q"     for Marvell Armada 1500-pro (BG2Q, 88DE3114)
+    "marvell,berlin3"      for Marvell Armada ? (BG3, 88DE????)
+
+
 PIT Timer required properties:
 - compatible: Should be "atmel,at91sam9260-pit"
 - reg: Should contain registers location and length
