[PATCH v6 0/6] PCI: uniphier: Add features for UniPhier PCIe host controller

From: Kunihiko Hayashi
Date: Fri Aug 07 2020 - 06:25:31 EST


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 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 (6):
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
dt-bindings: PCI: uniphier: Add iATU register description
PCI: uniphier: Add iATU register support
PCI: uniphier: Add error message when failed to get phy
