I'll diff this to the version in my tree and see what I can grab. I don't know 
if I'll find the time before November though.

Thanks to Navid for testing the driver on different hardware. I'm happy it just 
worked :-)

I plan to submit this myself eventually. Right now I don't think the state of 
zx297520v3 support is ready for SPI (no pinmux yet), and the code itself has a 
pile of todos.

If zx27 gets to the point where it has the prerequisites  are upstream first I 
can speed this up of course :-)
