IIO driver for ADC AD7321

For most of other ADC devices, IIO ( Industrial Input Output) is available.

But i can't able to find out IIO driver for AD7321.

But i got only AD7321 Evaluation Software from http://www.analog.com/en/products/analog-to-digital-converters/ad-converters/ad7321.html#product-evaluationkit.

Where can i get IIO driver for this ADC? Can any one help for me ..?
