+* Device tree bindings for Atmel SMC (Static Memory Controller)
+
+The SMC registers are used to configure Atmel EBI (External Bus Interface)
+to interface with standard memory devices (NAND, NOR, SRAM or specialized
+devices like FPGAs).
+
+Required properties:
+- compatible: Should be one of the following
+ "atmel,at91sam9260-smc", "syscon"
+ "atmel,sama5d3-smc", "syscon"
+- reg: Contains offset/length value of the SMC memory
+ region.
+
+Example:
+
+smc: smc@ffffc000 {
+ compatible = "atmel,sama5d3-smc", "syscon";
+ reg = <0xffffc000 0x1000>;
+};
