The 32.768 kHz clock inside the A80 SoC is fed from an external source, typically the AC100 RTC module. Make the osc32k placeholder a fixed-factor clock so board dts files can specify its source.

I'm guessing that an unresolved dependency when the driver has not loaded yet, or is not even compiled ? How is it working then?
