Linux-2.6.12-rc2v2.6.12-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!

This interface is defined by the Video Electronics Standards +Association (VESA). The standards are available for purchase at +http://www.vesa.org . The DDC bus is not yet supported because its register +is not directly memory-mapped. + +The second interface is a general-purpose I2C bus. This is the only +interface supported by the driver at the moment. + |
