I believe driver should, by default, set absmin and absmax to match the limits of the hardware/protocol. In your case it would be 1023. The driver may choose to accept additional infromation from platform data, if present, you can also adjust absmin/absmax etc via ioctl durng the bootup sequence. Hope this helps. -- Dmitry -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
