Thanks Daniel.
After creating devices using mknod, it is working on expected lines. After reboot these devices are getting removed and I need to create them manually every time.
Can you please suggest me the procedure to enable it programmatically ? I tried adding CONFIG_DEVTMPFS=y and CONFIG_DEVTMPFS_MOUNT=y in the def config, but no luck.
Thanks
Naresh

Please don't use top posting.
You can look into /sys/bus/iio/devices/iio:device0/dev and get the
MAJOR and MINOR,
then create the device node manually, using:
mknod /dev/iio:device0 c MAJOR MINOR
Not sure why are you mentioning /proc/devices here.
thanks,
Daniel.
