It does one thing ... it turns Droid 4 into useful phone!
Thanks a lot. I believe these are same patches as in droid4-pending-v5.7 branch, so whole series is

Getting this into 5.8 would be nice :-).

These work for me, and I have patched ofono with basic functionality. It is no longer possible to use minicom for debugging, but printf can be used instead, so that's not much of a problem.
I have adjusted ofono code, and moved away from normal AT support code. More API changes would not be welcome :-).
