This patchset add the driver and dt-bindings of the controller. Changes since v7: [6] - include files in alphabetical order - get rid of unused MACROs and variables - optimize meson_pcie_link_up() while loop - correct cover-letter version Changes since v6: [5] - fix bad usage of ERR_PTR(ENXIO) - fix meson_pcie_rd_own_conf() when read PCI_CLASS_DEVICE reg Changes since v5: [4] - update MAINTAINER file in alphabetical order - remove meaningless comment - use ERR_PTR function instead of (void *) cast - use is_power_of_2(size) instead of size & (size - 1) - add comment for PCI_CLASS_REVISION register operation 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 [4] : https://lkml.kernel.org/r/1539049990-30810-1-git-send-email-hanjie.lin@amlogic.com [5] : https://lkml.kernel.org/r/1542876836-191355-1-git-send-email-hanjie.lin@amlogic.com [6] : https://lkml.kernel.org/r/1544097760-85834-1-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 | 595 +++++++++++++++++++++ 5 files changed, 683 insertions(+) create mode 100644 Documentation/devicetree/bindings/pci/amlogic,meson-pcie.txt create mode 100644 drivers/pci/controller/dwc/pci-meson.c
