OK I was wondering what happened..

OK great thanks! It took me few hours of debugging to figure out that
it does not work on my blaze as I did not have the wl12xx card in it :)

Also can you fill in the missing GPIO lines for blaze from the schematics?

Yes that needs the two GPIO fixes posted by Jon Hunter last week.
One for patching in the GPIO trigger type to both omap4-sdp.dts, and
the other one is "gpio/omap: ensure gpio context is initialised".
