My thinking has been that the maintainers will more likely accept a series
of small patches than to make such a huge change to the entire driver, my
for-next tree is where I'm working on this, and I plan to post another set
of 15 patches soon, when I've fixed up some issues to do with probe/remove
cycles.

You should note that my for-next branch has moved on slightly since you
have taken this, because I have implemented device tree support and changed
the config download to use the request_firmware_async() function.

Your device tree stuff for mach-goni.c looks really useful, however - if
you can send me a patch for that against my current for-next branch I can
include it with my version of the device tree support.

all the best
