I had a look at it looks like it uses the API in a way that would fit nicely with my plans, ie, it should be possible to use the same driver on both archs pretty much without changes provided the ppc platform provides a clock source driver and hooks it up to the device-tree. I'll work on some proof-of-concept implementation of the core bits early next week.
