Subject: RTC class driver for ppc_md RTC functions
From: David Woodhouse <dwmw2@xxxxxxxxxxxxx>
This hooks up the platform-specific [gs]et_rtc_time functions so that kernels
using CONFIG_RTC_CLASS have RTC support on most PowerPC platforms.

If you say yes here you get support for the Ricoh RS5C313 RTC chips.
