commit ebcc3f57a4ff0b307dd0ef7b26b6b32392052707 Author: Gabe Black gabeblack@chromium.org Date: Tue Sep 24 01:25:02 2013 -0700
am335x: Add data structures for the clock module registers.
To avoid having to read/write raw addresses with magic constants, this change adds data structures which represent the clock module registers and some constants for how the clock module is used currently.
