Ooop, I did not realize that it is there as part of sysfs.h. I was looking for other header to get support for this. I can use this for proximity only but I think I should go with you other suggestion to implement this on channel basis. This will help also in future for other drivers to have different sampling on different channel. > Actually add it to the iio-core as an element in the info_mask as I > doubt this will be the last time > we see this control.

I will send the patch for implementing this first and then modified version of my driver which actually uses this one.
