SPI overlay not working in 4.1.15

Hello,
I was trying to play with SPI overlay but without success. I had it working on 3.8 kernel but with 4.1 it fails.
Device is created in /dev but no real communication on board.

It does not work with mine dtbo file or even with precompiled one (BB-SPIDEV0).

dmesg reports no errors:

Mine edited dts file i was trying it with:

Hello

I think I had a similar issue and noted it here. https://groups.google.com/forum/#!topic/beagleboard/gOynYr8fgns
also this sounds similar

bottom line=> can’t mux the pins using the command line echo method => I had to load the overlay using bone_capemgr.enable in uEnv.txt.

Maybe check with Charles Steinkuehler, he sounds like he knows this overlay stuff.
