This patch series adds PCIe legacy interrupt (INTx) support to the iProc PCIe driver by modeling it with its own IRQ domain. All 4 interrupts INTA, INTB, INTC, INTD share the same interrupt line connected to the GIC in the system. This is now modeled by using its own IRQ domain. Also update all relevant devicetree files to adapt to the new model This patch series is available on GIHUB: repo: https://github.com/Broadcom/arm64-linux.git branch: pcie-intx-v1 Ray Jui (6): PCI: iproc: Update iProc PCI binding for INTx support PCI: iproc: Add INTx support with better modeling arm: dts: Change PCIe INTx mapping for Cygnus arm: dts: Change PCIe INTx mapping for NSP arm: dts: Change PCIe INTx mapping for HR2 arm64: dts: Change PCIe INTx mapping for NS2 .../devicetree/bindings/pci/brcm,iproc-pcie.txt | 31 +++++-- arch/arm/boot/dts/bcm-cygnus.dtsi | 18 +++- arch/arm/boot/dts/bcm-hr2.dtsi | 18 +++- arch/arm/boot/dts/bcm-nsp.dtsi | 27 ++++-- arch/arm64/boot/dts/broadcom/northstar2/ns2.dtsi | 19 +++-- drivers/pci/host/pcie-iproc-platform.c | 2 + drivers/pci/host/pcie-iproc.c | 95 +++++++++++++++++++++- drivers/pci/host/pcie-iproc.h | 6 ++ 8 files changed, 188 insertions(+), 28 deletions(-) -- 2.1.4 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
