Please help with kernel configuration of RTC

Hi,

I need to access the Real-Time Clock (RTC) for power management (apmd/ apmsleep) via /dev/rtc. However, when the kernel is configured and build, the /dev/rtc still does not show up.

Below is the kernel's .config file (partially)

Thanks for any help or suggestions.

Best, Podi
