- Use PCI_INTERRUPT_* definitions from PCI core instead of custom ones
  (Pali Rohár)

- Derive MSI number from bit(s) set in PCIE_MSI_STATUS_REG, not from
  PCIE_MSI_PAYLOAD_REG (Pali Rohár)

- Align multi-MSI vectors to power of two (Pali Rohár)

- Rewrite IRQ code to use chained IRQ handler (Pali Rohár)

- Check return value of generic_handle_domain_irq() and warn about spurious
  interrupts (Pali Rohár)

- Make MSI irq_chip structures static to driver (Marek Behún)

- Make msi_domain_info structure static to driver (Marek Behún)

- Use dev_fwnode() instead of of_node_to_fwnode(dev->of_node) (Marek Behún)

- Refactor unmasking of summary MSI interrupt (Pali Rohár)

- Add support for masking MSI interrupts and leave them masked at setup
  (Pali Rohár)

- Set MSI doorbell address to address of struct advk_pcie (Pali Rohár)

- Enable MSI-X support (Pali Rohár)

- Add support for ERR interrupt on emulated bridge (Pali Rohár)

- Fix read of PCI_EXP_RTSTA_PME bit on emulated bridge (Pali Rohár)

- Optimize writing PCI_EXP_RTCTL_PMEIE and PCI_EXP_RTSTA_PME on emulated
  bridge (Pali Rohár)

- Add support for PME interrupts (Pali Rohár)

- Fix support for PME requester on emulated bridge (Pali Rohár)

- Use separate INTA interrupt for emulated Root Port so PME and AER
  interrupt is not shared with downstream devices (Pali Rohár)

- Remove irq_mask_ack() callback for INTx interrupts (Pali Rohár)

- Don't mask legacy INTx interrupts when mapping (Pali Rohár)

- Drop unnecessary "__maybe_unused" from advk_pcie_disable_phy() (Marek
  Behún)

- Update comment about why we check for link being up before issuing a
  config request (Marek Behún)
