Thanks for your patch!

Can you please use union vin_data and VIN_DATA_PIN_GROUP(), to reduce
redundancies, cfr. commit 9942a5b52990b8d5 ("pinctrl: sh-pfc: r8a7795:
Deduplicate VIN4 pin definitions")?
Or do you want to do that in a follow-up patch (which means more
review work)?

R-Car H3 and M3-W don't have the data8_sft8 groups yet (the BSP has).
IIRC, that's due to rcar-vin not yet supporting that mode. Niklas?

"A" groups without "B" groups? Usually we drop the "_A" suffix in that case.
They're actually named like that in hardware user manual rev. 1.00 (and no
update in the errata)?
