No. The name has to match the <name>-supply property present in the device's node, that's why we need this property :) > Also, I've seen devices that are split across two power domains. > These devices aren't CPUs, but they are other devices including > L2 caches.

Right, that's a good example of why we need multi-regulator support :) -- viresh -- 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
