Yes, this was suggested in the past and I spent some time looking into it. We have made a deliberate choice to implement this via sysfs rather than debugfs since it needs to work on devices that don't have debugfs enabled. In addition, there are some quirks about the way in which we have to read/write registers which means regmap isn't a good fit. -- 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
