Now, as Analog Input is working I can read and test a little bit for better understanding of how device tree overlays work.
Again, thanks a lot.

This link provides an excellent one page summary regarding capemgr and universal io:
https://groups.google.com/forum/#!category-topic/beagleboard/beaglebone-black-wireless/RewjY34TPYE
which provides this link:
https://github.com/cdsteinkuehler/beaglebone-universal-io
and for those who own a BBBW always read anything written by RobertCNelson:
https://groups.google.com/forum/#!categories/beagleboard/beaglebone-black-wireless
he is not hard to find. He is the guru geek of embedded Linux.
Once you have read through the BBBW forum you will understand what is required to configure wireless with connman.
Cheers,
Kevin.
