Hi Bjorn and Lorenzo,

PCI drivers use highly similar code block to allocate IRQ domain which
leads to code duplication than expected. This patchset adds a new helper,
pci_alloc_intx_irqd(), to avoid that as much as possible. Just leave
pcie-rockchip out now as it's under re-construct and will add incremental
patch for it if this series looks ok and the pcie-rockchip ongoing patches
got merge.


Changes in v2:
- fix typo and move the code to C file.

Shawn Lin (9):
  PCI: Add pci_alloc_intx_irqd() for allocating IRQ domain
  PCI: dra7xx: Use pci_alloc_intx_irqd() helper to simplify the code
  PCI: keystone-dw: Use pci_alloc_intx_irqd() helper to get irq domain
    for INTx
  PCI: aardvark: Use pci_alloc_intx_irqd() helper to get irq domain for
    INTx
  PCI: faraday: Use pci_alloc_intx_irqd() helper to get irq domain for
    INTx
  PCI: altera: Use pci_alloc_intx_irqd() helper to get irq domain for
    INTx
  PCI: mediatek: Use pci_alloc_intx_irqd() helper to get irq domain for
    INTx
  PCI: xilinx-nwl: Use pci_alloc_intx_irqd() helper to get irq domain
    for INTx
  PCI: xilinx: Use pci_alloc_intx_irqd() helper to get irq domain for
    INTx
