of overlay: how to insert new nodes with references to it

[Enrico Weigelt, metux IT consult]

Hello folks,


I'm trying to use an overlay to add several new nodes with references
between them (eg. a gpio controller and devices using the gpios).

Problem: dtc adds my new 'gpio1' node to the __fixups__ list, which is
used for resolving symbols against the live tree - obviously it can't
exist there, since it's added by the overlay. Therefore applying the
overlay fails:

    "OF: resolver: node label 'gpio1' not found in live devicetree
     symbols table"

Shouldn't the symbol be added to __local_fixups__ instead of __fixups__
?
How can I force dtc to do that ?
