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: 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() .../devicetree/bindings/pci/uniphier-pcie.txt | 1 + drivers/pci/controller/dwc/pcie-designware-host.c | 3 + drivers/pci/controller/dwc/pcie-designware.h | 1 + drivers/pci/controller/dwc/pcie-uniphier.c | 73 +++++++++++++++++----- 4 files changed, 63 insertions(+), 15 deletions(-) -- 2.7.4
