Ah, this is different GPIO controller that is listed in the DSDT (the Baytrail GPIO host controller). In order to get ACPI GPIO stuff work here you would need to first add the GPIO device to the ACPI namespace and then modify gpio-f7188x.c to probe it from there. You would also need to invent a _HID to the device in order to get it matched. Unfortunately using random _HID will make upstreaming the changes difficult. -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
