Hi,

This patchset adds support for the N950 modem. Afterwards it can be
used with ofono in the same way, that the N900's modem can be used [0].

In addition to the kernel patchset, ofono must be modified slightly, though.
The cbs interface from the N950 modem seems to be broken resulting in modem
reset. The below ofono patch is enough to get it running for the N950.

All of the patches are more or less mergable independent
of each other, so I suggest the following merging scheme:

This one should go in via Paul Walmsley.

I already took those via the HSI tree.

The DTS changes can go in via Tony's tree.
