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?
