You seem to also be adding a second chip name to the list here, which is
more than the patch subject/description imply you're doing...

"generic-pinconf" is too generic of a compatible value for this binding
to define.

Instead, I think you want to either:

a)

Use compatible="atmel,at91rm9200-pinctrl" for the old binding,
use compatible="atmel,at91rm9200-pinctrl-generic" for the new binding

or:

b)

Define Boolean property atmel,generic-pinconf (perhaps a better name
could be chosen?). If it's not present, parse the node assuming the old
binding. If it is present, parse the node assuming the new binding.
