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

Tested-by: Pavel Machek <pavel@xxxxxx>

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 :-).
