How about these options then? amstaos,proximity-diode-0-enabled; amstaos,proximity-diode-1-enabled; led-max-microamp = <100000>; Brian -- To unsubscribe from this list: send the line "unsubscribe linux-arm-msm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
