Could you squash the change below in this patch? And actually it's pretty easy to misuse the dfll read/write/wmb functions. We might want to have some generic functions for these, and let the generic functions handle the offset to different register blocks. > Indeed, having single readl/writel and handling the different register areas there sounds much better, I'll implement that.
