Yes, I am aware of the extra register, and that's reflected in the DRIF nodes definition within the SoC specific device trees. I'll tackle initialization and configuration of the extra register at some point, do you think we could use the default value for now? > > Gr{oetje,eeting}s, > > Geert > > > -- > Geert Uytterhoeven -- There's lots of Linux beyond ia32 -- geert@linux- > m68k.org > > In personal conversations with technical people, I call myself a hacker.

Yes, that's fine for me, if it works with the current driver. Gr{oetje,eeting}s, Geert
