For the record, I see the following DA9063 variants on the Renesas boards I have
access to:
  - DA9063 AD: Lager (R-Car H2), Koelsch (R-Car M2-W),
  - DA9063 BB: Gose (R-Car M2-N), Blanche (R-Car V2H), Alt (R-Car E2).

I cannot check Porter (R-Car M2-W) and Silk (R-Car E2) right now, but
from Marek's report, Porter has DA9063L CA.

Marek: which variant does your Stout (R-Car H2) have?

Thanks!

Gr{oetje,eeting}s,
