No need to change of_device_is_available() -- it handles the standards-compliant "okay" as well as "ok" which is non-compliant but probably exists in some broken real OF trees (and even if not, it's bad to break compatibility with older device trees without a good reason). Maybe add a comment indicating which should be used. -Scott _______________________________________________ devicetree-discuss mailing list [email protected] https://lists.ozlabs.org/listinfo/devicetree-discuss
