Oh no, its'called "avb0_mdio" here, but "avb(0)_mdc" on all other
R-Car Gen3 SoCs?


    Can you remember the reason? I don;t want to follow the bad example. :-)

Sorry, I don't know.

   Hm, you seem to have participated in the related discussions for H2/M3-W...
The reason was that omlu AVB_MDC signal was multiplexed, AVB_MDIO signal (and AVB MII signals) was mapped to a dedicated pin without any multiplexing, so the "avb_mdc" group initially contained only AVB_MDC.

Gr{oetje,eeting}s,
