A working rtc kernel driver is needed so that hwclock can synchronize system clock to rtc during shutdown/boot. We already have a rtc platform driver for power arch located at drivers/rtc/rtc-opal.c However it depends on CONFIG_RTC_CLASS which is disabled by default. So this driver is not compiled with pseries defconfig as rtc class support is missing from the kernel.
We fix this by enabling rtc class support in pseries defconfig so that this driver gets enabled and is compiled into the pseries kernel.
