Is this based a on a new version of the IP? Shall we make the second reg 
mandatory for the new HW? If I remember correctly the reg needs to be restored 
after power save event. So I suppose mmc won't work if that's not done. So 
optional wouldn't be the right approach.

Can you please clarify if that's the case.

Thanks,
Matthias
