I was wondering whether the gpio-controller nodes lack both the 'interrupt-controller' boolean flag as well as the '#interrupt-cells = <2>' property. The former may be optional, I'm not certain there. But the latter should be a hard requirement without which the 'funkyfpga' references cannot get parsed I'm afraid. Am I missing something? Did I get the names right? Shall I send a patch? Is the code working without those specs since it assumes knowledge that was not specified in the device tree? And would this be against the idea that the binding should be "complete" and independent of who is interpreting the data? Or is the binding document just incomplete? virtually yours Gerhard Sittig -- DENX Software Engineering GmbH, MD: Wolfgang Denk & Detlev Zundel HRB 165235 Munich, Office: Kirchenstr. 5, D-82194 Groebenzell, Germany Phone: +49-8142-66989-0 Fax: +49-8142-66989-80 Email: office@xxxxxxx -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
