2016-01-28HSI: nokia-modem: add n950 and n9 supportSebastian Reichel1-5/+7
The Nokia N950 and Nokia N9 also have a SSI connected modem, which use the same protocols as the Nokia N900, but with increased link speed (96000 kbps instead of 55000 kbps) and with less GPIOs. Since it's unclear, if the N950 and the N9 use exactly the same modem, each of them gets their own compatible string.

2014-05-16HSI: Introduce Nokia N900 modem driverSebastian Reichel1-0/+57

The handles the GPIOs for enabling and resetting the modem and instanciates ssi-protocol for data exchange. It does not yet support exchanging voice data with the modem.
