Pali Rohár <pali@kernel.org> writes: > PCI mvebu error interrupt source is triggered for non-INTx event. > So e.g. when AER or PME event occurs. > > This patch series adds support for reporting AER and PME interrupts on > Marvell PCIe Root Ports which allows use to kernel AER and PME drivers. > > Without this change kernel AER and PME drivers do not work at all. > > DT bindings for this support is currently provided only for Kirkwood and > Dove platforms as other new mvebu SoCs requires extension to armada IRQ > driver, which is currently disallowed. > > Without new DTS files, pci-mvebu.c driver acts as before this change, > there is no AER and PME kernel support. > > I have tested this change on Armada 385 board (with additional changes > to A385 DTS files and IRQ driver, not included there) and AER interrupt > is delivered to kernel AER driver correctly. > > Pali Rohár (4): > dt-bindings: PCI: mvebu: Update information about error interrupt > PCI: mvebu: Implement support for interrupts on emulated bridge > ARM: dts: kirkwood: Add definitions for PCIe error interrupts > ARM: dts: dove: Add definitions for PCIe error interrupts Applied both dts patches on mvebu/dt Thanks, Gregory > > .../devicetree/bindings/pci/mvebu-pci.txt | 1 + > arch/arm/boot/dts/dove.dtsi | 8 +- > arch/arm/boot/dts/kirkwood-6192.dtsi | 4 +- > arch/arm/boot/dts/kirkwood-6281.dtsi | 4 +- > arch/arm/boot/dts/kirkwood-6282.dtsi | 8 +- > arch/arm/boot/dts/kirkwood-98dx4122.dtsi | 4 +- > drivers/pci/controller/pci-mvebu.c | 256 ++++++++++++++++-- > 7 files changed, 252 insertions(+), 33 deletions(-) > > -- > 2.20.1 >
