Hi, This patch series add Mediatek Gen2 PCIe host controller driver and dt-binding document. It can be found on MT7623 series SoCs. This driver was validated using Broadcom Tigon3 and Intel(R) 82575/82576 gigabit ethernet card. Changes since v5: - rebase to Linux 4.12-rc1. - remove redundant module.h header and MODULE macros. Changes since v4: - move the per-port registers to the parent node. - use a valid compatible for hifsys controller. - use the 'sysirq' instead of 'gic' as a correct 'interrupt-parent' of the interrupt-map properties. 'sysirq' is an interrupt-controller that could help us to reverse GIC SPIs polarity so that we could properly set irq type to level low without any extra properties. It was a mistake to select wrong interrupt-parent on the previous versions. Now, we could remove unnecessary interrupt properties entirely from binding. Changes since v3: - correct sub-nodes unit addresses. Changes since v2: - modify Kconfig to avoid kbuild test error on some architecture. - change compatible string. - revise binding document: add missing interrupt-names. remove the board dts example and drop 'status' properties. remove unnecessary descriptions bout standard PCI bus binding. Changes since v1: - add .suppress_bind_attrs. - remove unnecessary *_valid_device() pattern. - remove PCI_PROBE_ONLY. - use the regular readl() instead of readl_relaxed(). - add .map_bus() and change to use pci_generic_config_read/pci_generic_config_write. - revise dt-binding document and move nonstandard properties to root node. - change compatible string. - use interrupt-map property and replace mtk_pcie_map_irq() with of_irq_parse_and_map_pci(). - use the new pci_register_host_bridge() method instead of pci_scan_root_bus()* Ryder Lee (2): PCI: mediatek: Add Mediatek PCIe host controller support dt-bindings: pcie: Add documentation for Mediatek PCIe .../bindings/pci/mediatek,mt7623-pcie.txt | 130 +++++ drivers/pci/host/Kconfig | 11 + drivers/pci/host/Makefile | 1 + drivers/pci/host/pcie-mediatek.c | 553 +++++++++++++++++++++ 4 files changed, 695 insertions(+) create mode 100644 Documentation/devicetree/bindings/pci/mediatek,mt7623-pcie.txt create mode 100644 drivers/pci/host/pcie-mediatek.c -- 1.9.1
