1* Device tree bindings for Atmel SMC (Static Memory Controller)
2
3The SMC registers are used to configure Atmel EBI (External Bus Interface)
4to interface with standard memory devices (NAND, NOR, SRAM or specialized
5devices like FPGAs).
6
7Required properties:
8- compatible:		Should be one of the following
9			"atmel,at91sam9260-smc", "syscon"
10			"atmel,sama5d3-smc", "syscon"
11			"atmel,sama5d2-smc", "syscon"
12			"microchip,sam9x60-smc", "syscon"
13			"microchip,sam9x7-smc", "atmel,at91sam9260-smc", "syscon"
14- reg:			Contains offset/length value of the SMC memory
15			region.

17Example:

19smc: smc@ffffc000 {
20	compatible = "atmel,sama5d3-smc", "syscon";
21	reg = <0xffffc000 0x1000>;
22};
