---------------------------
-What: i2c-rpx driver
-When: June 2007
-Why: Broken. It depends on i2c-algo-8xx which has never been in the
- mainline kernel.
-Who: Jean Delvare <khali@...ux-fr.org>

----------------------------
-
What: legacy RTC drivers (under drivers/i2c/chips)
When: November 2007
Why: Obsolete. We have a RTC subsystem with better drivers.
