ACPICA: Implicit notify support
This feature provides an automatic device notification for wake devices when a wakeup GPE occurs and there is no corresponding GPE method or handler. Rather than ignoring such a GPE, an implicit AML Notify operation is performed on the parent device object. This feature is not part of the ACPI specification and is provided for Windows compatibility only. Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
