Hi all, This series includes a couple of changes to the PCI power management that should make Linux follow the PCIe spec better and also support for sibling PCIe devices sharing ACPI power resources. The issues this series aims to solve came up with Intel Ice Lake Thunderbolt enabling where the controller is first time integrated into the SoC but I think these issues are generic to any platform having similar configuration.
