Is there a reason this file can't be a platform driver?

Not that I know of, I did it like this only because the other in-tree MMP clk drivers do so. I guess the initialization should look like any of the qcom GCC drivers then?

While at it, do you think the other MMP clk drivers could use a conversion?
