Hi Geert Thank you for your feedback > My worry is not about the group of pins marked _X, but about its > siblings without _X.

Yes. > I agree it is unlikely to become an issue with TCLK soon, but (H)SCIF1 > are more likely to become enabled, also on real products. Yeah. But *current* product (White Hawk) is using (H)SCIF0 which doesn't have rename issue. I think we don't need to super care about not used SCIF for now (?), at least it is following *current* latest datasheet. If you can accept about it, I will post v4 patch-set soon, and will post naming update patch when new datasheet coming. If you can't, I will wait new datasheet, and post v4 patch-set which is including naming update. But one note here is that we don't know when the new datasheet will comming, and we don't know it solves all naming issue and/or there will be no more naming issue. Thank you for your help !!
