What about wake events for other PCIe controllers? Do we need/want to
distinguish by name for those?
Thierry
Only one wake gpio is defined for PCIe in Tegra234. 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.
