+* Device tree bindings for Atmel Bus Matrix
+
+The Bus Matrix registers are used to configure Atmel SoCs internal bus
+behavior (master/slave priorities, undefined burst length type, ...)
+
+Required properties:
+- compatible:          Should be one of the following
+                       "atmel,at91sam9260-matrix", "syscon"
+                       "atmel,at91sam9261-matrix", "syscon"
+                       "atmel,at91sam9263-matrix", "syscon"
+                       "atmel,at91sam9rl-matrix", "syscon"
+                       "atmel,at91sam9g45-matrix", "syscon"
+                       "atmel,at91sam9n12-matrix", "syscon"
+                       "atmel,at91sam9x5-matrix", "syscon"
+                       "atmel,sama5d3-matrix", "syscon"
+- reg:                 Contains offset/length value of the Bus Matrix
+                       memory region.
+
+Example:
+
+matrix: matrix@ffffec00 {
+       compatible = "atmel,sama5d3-matrix", "syscon";
+       reg = <0xffffec00 0x200>;
+};
