that's your problem :-)
You can just as well create both nodes in DTS file:
ci13xx_fsl at foo {
compatible = "fsl,chipidea";
reg = <foo size>;
blablabla
ranges;
chipidea_core at bar {
compatible = "chipidea";
reg <bar size>;
blablabla
};
};
then assign the regulator to chipidea itself, not to the glue.
