Subject[patch 2.6.19-git] RTC Kconfig sorted by type
Date
This reorders the RTC driver menu into separate sections, splitting out
the SOC, I2C, and SPI support to help make the menu easier to navigate.
(We got some feedback a while ago that it was "a mess" and hard to make
sense of...)

Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

---
Assumes the rtc-omap patch has been merged, and no other RTC drivers
have been added to this Kconfig menu.
