RTC class drivers and powerpc arch

Hi,

Since todc was removed from arch/powerpc I wonder how to use the rtc-cmos
RTC class driver for my AmigaOne with its VIA southbridge. Do I have to
define a platform device and the get/set_rtc_time hook functions or can
the driver probe for and access the hardware automatically, if there's a
device node for the RTC in the device tree?

Thanks!

regards,

Gerhard
