You might want to mention that a single entry ("specifier") is expected in the list. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

In general, a device may have more than one interrupt output. Hence in general, the interrupts property is a list of 1 or more interrupt specifiers. In this case, that list should be a single entry. The binding should state this. how about: ---------- Optional properties: interrupts: Contains a single interrupt specifier which describes the LM90 XXXX output. See interrupt-controller/interrupts.txt for the format. ---------- (where you'd replace XXXX with the pin/signal name from the datasheet). -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
