[0/3] Use xilinx controller irq for AER handler

Message

Xilinx ZynqMP PS PCIe does not report AER interrupts using Advanced
Error Interrupt Message Number. The controller has dedicated interrupt line
for reporting PCIe errors along with AER.

Since pcie-xilinx-nwl.c is platform driver and AER uses irq from
pci_dev, using struct device_node private data to save xilinx controller
error irq line. Using PCI quirks this data is passed to sysdata of
root port pci_dev which is retrieved and used for AER handler registration.


Bharat Kumar Gogada (3):
  PCI: xilinx-nwl: Save error IRQ number in device_node private data
  PCI: Use dedicated Xilinx controller irq number for AER
  PCI/portdrv: Add support for sharing xilinx controller irq with AER
