I tried out this patch briefly and it appears to work. At least I could get proper interrupt events on ADC pins on Galileo 2. However, we should IMHO move this patch below the custom "drive" property patch in the kernel git tree (and modify the drive property patch accordingly). This patch could then be submitted to real kernel upstream because it wouldn't depend on patches that can't upstreamed.
