AM3359: ADC driver limitations

Part Number: AM3359

Hi all,

I would like to know about "ADC Driver Limitations" on the following link.

http://processors.wiki.ti.com/index.php/Linux_Core_ADC_Users_Guide

ADC Driver Limitations

This driver is based on the IIO (Industrial I/O subsystem), however this driver has limited functionality:

1. 1. "Out of Range" not supported by ADC driver.

What are the benefits if the above "a" is supported?

Best regards.
