So the same property specified again in vf500-colibri-eval-v3.dts? Ok will include the same. - Sanchayan. -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
