There was a previous attempt to upstream this some years ago[1] but was blocked as most STB PCIe integrations have a sparse DMA mapping[2] which is something currently not supported by the kernel. Luckily this is not the case for the Raspberry Pi 4. Note that the driver code is to be based on top of Rob Herring's series simplifying inbound and outbound range parsing. [1] https://patchwork.kernel.org/cover/10605933/ [2] https://patchwork.kernel.org/patch/10605957/ Reviewed-by: Chuck Lever Reviewed-by: Martin Habets --- Changes since v3: - Moved all the log2.h related changes at the end of the series, as I presume they will be contentious and I don't want the PCIe patches to depend on them. Ultimately I think I'll respin them on their own series but wanted to keep them in for this submission just for the sake of continuity. - Addressed small nits here and there. Changes since v2: - Redo register access in driver avoiding indirection while keeping the naming intact - Add patch editing ARM64's config - Last MSI cleanups, notably removing MSIX flag - Got rid of all _RB writes - Got rid of all of_data - Overall churn removal - Address the rest of Andrew's comments Changes since v1: - add generic rounddown/roundup_pow_two64() patch - Add MAINTAINERS patch - Fix Kconfig - Cleanup probe, use up to date APIs, exit on MSI failure - Get rid of linux,pci-domain and other unused constructs - Use edge triggered setup for MSI - Cleanup MSI implementation - Fix multiple cosmetic issues - Remove supend/resume code Jim Quinlan (3): dt-bindings: PCI: Add bindings for brcmstb's PCIe device PCI: brcmstb: Add Broadcom STB PCIe host controller driver PCI: brcmstb: Add MSI support Nicolas Saenz Julienne (5): ARM: dts: bcm2711: Enable PCIe controller MAINTAINERS: Add brcmstb PCIe controller arm64: defconfig: Enable Broadcom's STB PCIe controller linux/log2.h: Fix 64bit calculations in roundup/down_pow_two() linux/log2.h: Use roundup/dow_pow_two() on 64bit calculations .../bindings/pci/brcm,stb-pcie.yaml | 97 ++ MAINTAINERS | 4 + arch/arm/boot/dts/bcm2711.dtsi | 37 + arch/arm64/configs/defconfig | 1 + drivers/acpi/arm64/iort.c | 2 +- drivers/clk/clk-divider.c | 8 +- drivers/clk/sunxi/clk-sunxi.c | 2 +- drivers/infiniband/hw/hfi1/chip.c | 4 +- drivers/infiniband/hw/hfi1/init.c | 4 +- drivers/infiniband/hw/mlx4/srq.c | 2 +- drivers/infiniband/hw/mthca/mthca_srq.c | 2 +- drivers/infiniband/sw/rxe/rxe_qp.c | 4 +- drivers/iommu/intel-iommu.c | 4 +- drivers/iommu/intel-svm.c | 4 +- drivers/iommu/intel_irq_remapping.c | 2 +- drivers/net/ethernet/amd/xgbe/xgbe-ethtool.c | 4 +- drivers/net/ethernet/marvell/sky2.c | 2 +- drivers/net/ethernet/mellanox/mlx4/en_clock.c | 3 +- drivers/net/ethernet/rocker/rocker_hw.h | 4 +- drivers/net/ethernet/sfc/ef10.c | 2 +- drivers/net/ethernet/sfc/efx.h | 2 +- drivers/net/ethernet/sfc/falcon/efx.h | 2 +- drivers/of/device.c | 3 +- drivers/pci/controller/Kconfig | 9 + drivers/pci/controller/Makefile | 1 + .../pci/controller/cadence/pcie-cadence-ep.c | 3 +- drivers/pci/controller/cadence/pcie-cadence.c | 3 +- drivers/pci/controller/pcie-brcmstb.c | 1008 +++++++++++++++++ drivers/pci/controller/pcie-rockchip-ep.c | 5 +- drivers/pci/msi.c | 2 +- include/linux/log2.h | 44 +- kernel/dma/direct.c | 2 +- kernel/kexec_core.c | 3 +- lib/rhashtable.c | 2 +- net/sunrpc/xprtrdma/verbs.c | 2 +- 35 files changed, 1211 insertions(+), 72 deletions(-) create mode 100644 Documentation/devicetree/bindings/pci/brcm,stb-pcie.yaml create mode 100644 drivers/pci/controller/pcie-brcmstb.c
