[PATCH 00/33] fsi: Interrupt support

This series primarily adds interrupt support to the FSI driver subsystem.
The series first improves the clocking model in the FSI core to provide
real clock rates to the engine drivers. Then there are various quality,
trace, and organizational improvements.
Another substantial part of the series is to make some master code common
through the use of a regmap to access master structures. This will prove
more useful as additional FSI master drivers are added.
Finally, interrupt support is added to the I2C driver as an alternative to
polling.
