This patchset add the driver and dt-bindings of the controller. Changes since v4: [3] - fix kbuild test robot and compile warnings Changes since v3: [2] - modify subject format - update Kconfig - update MAINTAINER file - add comment and error handle for meson_pcie_get_mem_shared() - drop useless initialization code - add comment for meson_size_to_payload() - optimize meson_pcie_establish_link() return code - optimize meson_pcie_enable_interrupts() redundant function - drop device_attch related code - drop dw_pcie_ops read_dbi and write_dbi function - add error handle for meson_add_pcie_port() when probe Changes since v2: [1] - abandon phy driver, move reset to the controller - use devm_add_action_or_reset() to use clock res - format correcting Changes since v1: [0] - use gpio lib instead open code - move 'apb' and 'port' reset from phy driver - format correcting [0] : https://lkml.kernel.org/r/1534227522-186798-1-git-send-email-hanjie.lin@amlogic.com [1] : https://lkml.kernel.org/r/1535096165-45827-1-git-send-email-hanjie.lin@amlogic.com [2] : https://lkml.kernel.org/r/1537509820-52040-1-git-send-email-hanjie.lin@amlogic.com [3] : https://lkml.kernel.org/r/1538999834-156423-3-git-send-email-hanjie.lin@amlogic.com Yue Wang (2): dt-bindings: PCI: meson: add DT bindings for Amlogic Meson PCIe controller PCI: amlogic: Add the Amlogic Meson PCIe controller driver .../devicetree/bindings/pci/amlogic,meson-pcie.txt | 70 +++ MAINTAINERS | 7 + drivers/pci/controller/dwc/Kconfig | 10 + drivers/pci/controller/dwc/Makefile | 1 + drivers/pci/controller/dwc/pci-meson.c | 593 +++++++++++++++++++++ 5 files changed, 681 insertions(+) create mode 100644 Documentation/devicetree/bindings/pci/amlogic,meson-pcie.txt create mode 100644 drivers/pci/controller/dwc/pci-meson.c
