Ok, I will add new property cs-chipselect like following :

ti,cs-chipselect:	number of chipselect. Indicates on the
			aemif driver which chipselect is used
			for accessing the memory.
			For compatibles "ti,davinci-aemif" and 
			"ti,keystone-aemif" it can be in range [0-3].
			For compatible "ti,omap-L138-aemif" range is [2-5].

Is it OK?
