* mfd: AB8500 system control driverMattias Nilsson2011-03-231-0/+80
This adds a pretty straight-forward system control driver for the AB8500. This driver will be used from the core platform, e.g the clock tree implementation in the machine code, and is by nature singleton. There are a few simple functions to read, write, set and clear registers so that the machine code can control its own foundation.
