Message

The original subject up to v6 is
"PCI: uniphier: Add features for UniPhier PCIe host controller".

This adds a new function called by MSI handler in DesignWare PCIe framework,
that invokes PME and AER funcions to detect the factor from SoC-dependent
registers.

The iATU patches is split from this series as
"PCI: dwc: Move iATU register mapping to common framework".

Changes since v8:
- Add uniphier_pcie_host_init_complete() that finds PME/AER vIRQ number
  after calling dw_pcie_host_init()
- Add conditions to depend on CONFIG_PCIE_PME and CONFIG_PCIEAER instead
  of CONFIG_PCIEPORTBUS
- Add Acked-by: line to portdrv patch

Changes since v7:
- Add Reviewed-by: line to 1st and 3rd patches

Changes since v6:
- Separate patches for iATU and phy error from this series
- Add Reviewed-by: line to dwc patch

Changes since v5:
- Add pcie_port_service_get_irq() function to pcie/portdrv
- Call pcie_port_service_get_irq() to get vIRQ interrupt number for PME/AER
- Rebase to the latest linux-next branch,
  and remove devm_platform_ioremap_resource_byname() replacement patch

Changes since v4:
- Add Acked-by: line to dwc patch

Changes since v3:
- Move msi_host_isr() call into dw_handle_msi_irq()
- Move uniphier_pcie_misc_isr() call into the guard of chained_irq
- Use a bool argument is_msi instead of pci_msi_enabled()
- Consolidate handler calls for the same interrupt
- Fix typos in commit messages

Changes since v2:
- Avoid printing phy error message in case of EPROBE_DEFER
- Fix iATU register mapping method
- dt-bindings: Add Acked-by: line
- Fix typos in commit messages
- Use devm_platform_ioremap_resource_byname()

Changes since v1:
- Add check if struct resource is NULL
- Fix warning in the type of dev_err() argument

Kunihiko Hayashi (3):
  PCI: portdrv: Add pcie_port_service_get_irq() function
  PCI: dwc: Add msi_host_isr() callback
  PCI: uniphier: Add misc interrupt handler to invoke PME and AER
