This series adds PCIe host controller driver for Socionext UniPhier SoCs. This controller is based on the DesignWare PCIe core. This driver supports LD20 and PXs3 SoCs. v4: https://www.spinics.net/lists/linux-pci/msg78278.html About legacy IRQ, it might be necessary to share common view from keystone driver that have been cleaned up[1]. [1] https://lore.kernel.org/patchwork/patch/989541/ Changes since v4: - fix an issue of using the wrong value to mask IRQ mask register Changes since v3: - dt-bindings: fix INTX numbering of legacy interrupt map - change interrupts to level ones - remove .xlate function - merge uniphier_pcie_ltssm_disable() into uniphier_pcie_ltssm_enable() - remove an error message on uniphier_pcie_establish_link() - change the order between irq_domain_add_liniear() and irq_set_chained_handler_and_data() - replace dummy_irq_chip with uniphier_pcie_irq_chip and its functions - add dependency on CONFIG_HAS_IOMEM - MAINTAINERS: add pcie-uniphier entry Changes since v2: - dt-bindings: remove a comment that the node name isn't important - dt-bindings: remove "intx" interrupt - dt-bindings: define 'legacy-interrupt-controller' node and its properties - return an error value when link up fails - remove devm_request_irq() and a handler for MSI IRQ - use chained interrupt instead of devm_request_irq() for legacy IRQ - add unipher_pcie_config_legacy_irq() to get legacy IRQ from 'legacy-interrupt controller' node - replace 4 statments to handle INTX with for_each_set_bit() - remove initialization of pp->root_bus_nr - remove indivisual interrupt enable bit definitions - rename 'irq_domain' member to 'legacy_irq_domain' in private structure - use pci_irqd_intx_xlate() for irq_domain_ops.xlate function Changes since v1: - follow capitalization conventions in the descriptions - use C style comments except for the SPDX line Kunihiko Hayashi (2): dt-bindings: PCI: Add UniPhier PCIe host controller description PCI: uniphier: Add UniPhier PCIe host controller support .../devicetree/bindings/pci/uniphier-pcie.txt | 81 ++++ MAINTAINERS | 7 + drivers/pci/controller/dwc/Kconfig | 10 + drivers/pci/controller/dwc/Makefile | 1 + drivers/pci/controller/dwc/pcie-uniphier.c | 471 +++++++++++++++++++++ 5 files changed, 570 insertions(+) create mode 100644 Documentation/devicetree/bindings/pci/uniphier-pcie.txt create mode 100644 drivers/pci/controller/dwc/pcie-uniphier.c -- 2.7.4
