Do we need/want to distinguish by name for those? Thierry

There is no implementation withinPCIe controller, so any wake capable gpio can be used for PCIe wake. As of now wedon't have a platform where different wake pins connected to PCIe slot. If any platform use new pins for PCIe wake then we can add to this list. Manikanta
