Subject: [PATCH v3 0/6] PCI: uniphier: Add features for UniPhier PCIe host controller

This series adds some features for UniPhier PCIe host controller.

- Add support for PME and AER invoked by MSI interrupt
- Add iATU register view support for PCIe version >= 4.80
- Add an error message when failing to get phy driver

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.

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 (6):
  PCI: dwc: Add msi_host_isr() callback
  PCI: uniphier: Add misc interrupt handler to invoke PME and AER
  dt-bindings: PCI: uniphier: Add iATU register description
  PCI: uniphier: Add iATU register support
  PCI: uniphier: Add error message when failed to get phy
  PCI: uniphier: Use devm_platform_ioremap_resource_byname()
