Subject: [PATCH 0/3] PCI: Power management improvements
Date: Wed,  5 Jun 2019 17:58:17 +0300
Message-ID: <20190605145820.37169-1-mika.westerberg@linux.intel.com> (raw)

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.

Mika Westerberg (3):
  PCI: Add missing link delays required by the PCIe spec
  PCI: Do not poll for PME if the device is in D3cold
  PCI / ACPI: Handle sibling devices sharing power resources
