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