we have a few i.MX6 Modules (imx6q-phytec-pfla02) with DA9063 PMICs that
all report the model/revision ID as 0x61/0x03. Those are marked as
follows:
    dialog DA9063 44 1240EHDA
    dialog DA9063 44 1312ECAF
We now have received a report from Phytec that those PMICs were not
marketed as preproduction in any way, but as a normal mask revision.
Their Dialog Semiconductor contact talked about AD, BA, and BB silicon
variants. How do those relate to the variant register value and to the
markings on the chips?
There seems to be a serious miscommunication somewhere.

regards
Philipp
