From: Daire McNamara <daire.mcnamara@xxxxxxxxxxxxx> This patchset adds support for the Microchip PCIe PolarFire PCIe controller when configured in host (Root Complex) mode. Updates since v16: * Patch needs CONFIG_PCI_HOST_COMMON. Add this to Kconfig stanza Updates since v15: * Call platform_set_drvdata earlier in devm_pci_alloc_host_bridge() * Use host_common_probe() and an init function to set up hw windows * status is u32 in mc_pcie_isr() * Removed mask var in mc_mask_intx_irq(), mc_unmask_intx_irq() * irq var is now signed in mc_platform_init() Updates since v14: * Removed cfg_read/cfg_write inline functions * Updated to irq_data_get_irq_chip_data() * Updated to use devm_platform_ioremap_resource() * Replaced of_pci_range parsing to setup windows via bridge pointer. Updates since v13: * Refactored to use pci_host_common_probe() Updates since v12: * Capitalised commit messages. Use specific subject line for dt-bindings Updates since v11: * Adjusted so yaml file passses make dt_binding_check Updates since v10: * Adjusted driver as per Rob Herring's comments, notably: - use common PCI_MSI_FLAGS defines - reduce storage of unnecessary vars in mc_pcie struct - switched to read/write relaxed variants - extended lock in msi_domain_alloc routine - improved 32bit safety, switched from find_first_bit() to ilog2() - removed unnecessary twiddle of eCAM config space Updates since v9: * Adjusted commit logs * make dt_bindings_check passes Updates since v8: * Refactored as per Rob Herring's comments: - bindings in schema format - Adjusted licence to GPLv2.0 - Refactored access to config space between driver and common eCAM code - Adopted pci_host_probe() - Miscellanous other improvements Updates since v7: * Build for 64bit RISCV architecture only Updates since v6: * Refactored to use common eCAM driver * Updated to CONFIG_PCIE_MICROCHIP_HOST etc * Formatting improvements * Removed code for selection between bridge 0 and 1 Updates since v5: * Fixed Kconfig typo noted by Randy Dunlap * Updated with comments from Bjorn Helgaas Updates since v4: * Fix compile issues. Updates since v3: * Update all references to Microsemi to Microchip * Separate MSI functionality from legacy PCIe interrupt handling functionality Updates since v2: * Split out DT bindings and Vendor ID updates into their own patch from PCIe driver. * Updated Change Log Updates since v1: * Incorporate feedback from Bjorn Helgaas Daire McNamara (3): PCI: Call platform_set_drvdata earlier in devm_pci_alloc_host_bridge dt-bindings: PCI: microchip: Add Microchip PolarFire host binding PCI: microchip: Add host driver for Microchip PCIe controller .../bindings/pci/microchip,pcie-host.yaml | 93 +++ drivers/pci/controller/Kconfig | 10 + drivers/pci/controller/Makefile | 1 + drivers/pci/controller/pci-host-common.c | 4 +- drivers/pci/controller/pcie-microchip-host.c | 541 ++++++++++++++++++ 5 files changed, 647 insertions(+), 2 deletions(-) create mode 100644 Documentation/devicetree/bindings/pci/microchip,pcie-host.yaml create mode 100644 drivers/pci/controller/pcie-microchip-host.c base-commit: c4d6fe7311762f2e03b3c27ad38df7c40c80cc93 prerequisite-patch-id: b98abc1ad412692a95e3eb3f7adfaff214750282 prerequisite-patch-id: b77f4eea4090304b5c113e4ccc29e64fc82cdc45 -- 2.25.1
