+* Device tree bindings for Atmel EBI
+
+The External Bus Interface (EBI) controller is a bus where you can connect
+asynchronous (NAND, NOR, SRAM, ....) and synchronous memories (SDR/DDR SDRAMs).
+The EBI provides a glue-less interface to asynchronous memories through the SMC
+(Static Memory Controller).
+
+Required properties:
+
+- compatible:		"atmel,at91sam9260-ebi"
+			"atmel,at91sam9261-ebi"
+			"atmel,at91sam9263-ebi0"
+			"atmel,at91sam9263-ebi1"
+			"atmel,at91sam9rl-ebi"
+			"atmel,at91sam9g45-ebi"
+			"atmel,at91sam9x5-ebi"
+			"atmel,sama5d3-ebi"
+
+- reg:			Contains offset/length value for EBI memory mapping.
+			This property might contain several entries if the EBI
+			memory range is not contiguous
+
+- #address-cells:	Must be 2.
+			The first cell encodes the CS.
+			The second cell encode the offset into the CS memory
+			range.
+
+- #size-cells:		Must be set to 1.
+
+- ranges:		Encodes CS to memory region association.
+
+- clocks:		Clock feeding the EBI controller.
+			See clock-bindings.txt
+
+Children device nodes are representing device connected to the EBI bus.
+
+Required device node properties:
+
+- #reg:			Contains the chip-select id, the offset and the length
+			of the memory region requested by the device.
+
+EBI bus configuration associated with specific chip-select will be defined in
+the configs subnode. This configs node will in turn contain several subnodes
+named config-<cs-id>, each of them containing the following properties.
+
+Optional config-<cs-id> node properties:
+
+- atmel,bus-width:		width of the asynchronous device's data bus
+				8, 16 or 32.
+				Default to 8 when undefined.
+
+- atmel,byte-access-type	"write" or "select" (see Atmel datasheet).
+				Default to "select" when undefined.
+
+- atmel,read-mode		"nrd" or "ncs".
+				Default to "ncs" when undefined.
+
+- atmel,write-mode		"nwe" or "ncs".
+				Default to "ncs" when undefined.
+
+- atmel,exnw-mode		"disabled", "frozen" or "ready".
+				Default to "disabled" when undefined.
+
+- atmel,page-mode		enable page mode if present. The provided value
+				defines the page size (supported values: 4, 8,
+				16 and 32).
+
+- atmel,tdf-mode:		"normal" or "optimized". When set to
+				"optimized" the data float time is optimized
+				depending on the next device being accessed
+				(next device setup time is subtracted to the
+				current device data float time).
+				Default to "normal" when undefined.
+
+Mandatory timings expressed in nanoseconds (see Atmel datasheet for a full
+description).
