Subject[PATCH v5 0/4] Simplify PCIe native ownership detection logic
Date
From: Kuppuswamy Sathyanarayanan <sathyanarayanan.kuppuswamy@linux.intel.com>

Currently, PCIe capabilities ownership status is detected by
verifying the status of pcie_ports_native, pcie_ports_dpc_native
and _OSC negotiated results (cached in struct pci_host_bridge
->native_* members). But this logic can be simplified, and we can
use only struct pci_host_bridge ->native_* members to detect it.

This patchset removes the distributed checks for pcie_ports_native,
pcie_ports_dpc_native parameters.

Changes since v4:
* Changed the patch set title (Original link: https://lkml.org/lkml/2020/5/26/1710)
* Added AER/DPC dependency logic cleanup fixes.

Kuppuswamy Sathyanarayanan (4):
ACPI/PCI: Ignore _OSC negotiation result if pcie_ports_native is set.
ACPI/PCI: Ignore _OSC DPC negotiation result if pcie_ports_dpc_native
is set.
PCI/portdrv: Remove redundant pci_aer_available() check in DPC enable
logic
PCI/DPC: Move AER/DPC dependency checks out of DPC driver
