The bindings don't fix the values for static power, but just provides a field for platforms to use. Everyone can then send its own power figures. Why do you thing it can't be generalized? > Actually, static power is optional since dynamic power is much more than > static power. Maybe, we should still capture it. @Javi ? -- 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
