I remember having noticed that problem, too, some time ago, but forgot
to fix/report it.

Some other machines (e.g. imx51-babbage) use a big group named after the
machine for all pin groups. Would it be nice to have a uniform rule
here?

I think this grouping is a relict from the time when we considered to
list the groups in the imx$num.dtsi? I would prefer to "fix" the driver
to work with the way imx25-karo-tx25 presents the pinmuxing because I
don't see the motivation for this extra grouping. (So let us define the
current method of imx25-karo-tx25 as the good one to follow if you ask
me.)

Best regards
Uwe
