Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2 
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

/* Offsets to the device registers.
Unlike software-only systems, device drivers interact with complex hardware.
It's not useful to define symbolic names for every register bit in the
device. The name can only partially document the semantics and make
the driver longer and more difficult to read.
In general, only the important configuration values or bits changed
multiple times should be defined symbolically.
