Stefan, there are some 'what is going on?' questions in here you might
want to answer!
I'll give it a try.

I found a datasheet at
http://www.st.com/st-web-ui/static/active/en/resource/technical/document/reference_manual/DM00034813.pdf
THis is one of a number I think.. Not sure which parts will work out of
the box
with this driver though... Stefan? What was it written against?
I wrote and tested this driver for the SPEAr600 in 2011/2012. The manual
mentioned above didn't exist at that time. I used one called
"UM510_rev3.0.pdf" from Feb 2011. If interested I can send you the
manual I used at that time.
I don't have access to the SPEAr600 hardware anymore. I'm afraid but I
can't be of much help here.
Thanks,
Stefan
