The PCIe controller in AM654 uses Synopsys core revision 4.90a and uses the same TI wrapper as used in keystone2 with certain modification. Hence AM654 will use the same pci wrapper driver pci-keystone.c This series was initially part of [1]. This series only includes patches that has to be merged via Lorenzo's tree. The PHY patches and dt patches will be sent separately. This series is created over my keystone MSI cleanup series [2] and EPC features series [3]. This series: *) Cleanup pci-keystone driver so that both RC mode and EP mode of AM654 can be supported *) Modify epc-core to support allocation of aligned buffers required for AM654 *) Fix ATU unroll identification *) Add support for both host mode and device mode in AM654 [1] -> https://lore.kernel.org/patchwork/cover/989487/ [2] -> https://www.mail-archive.com/linux-kernel@vger.kernel.org/msg1883081.html [3] -> https://www.mail-archive.com/linux-kernel@vger.kernel.org/msg1899011.html Kishon Vijay Abraham I (24): PCI: keystone: Add start_link/stop_link dw_pcie_ops PCI: keystone: Cleanup error_irq configuration dt-bindings: PCI: keystone: Add "reg-names" binding information PCI: keystone: Perform host initialization in a single function PCI: keystone: Use platform_get_resource_byname to get memory resources PCI: keystone: Move initializations to appropriate places dt-bindings: PCI: Add dt-binding to configure PCIe mode PCI: keystone: Explicitly set the PCIe mode dt-bindings: PCI: Document "atu" reg-names PCI: dwc: Enable iATU unroll for endpoint too PCI: dwc: Fix ATU identification for designware version >= 4.80 PCI: keystone: Prevent ARM32 specific code to be compiled for ARM64 dt-bindings: PCI: Add PCI RC dt binding documentation for AM654 PCI: keystone: Add support for PCIe RC in AM654x Platforms PCI: keystone: Invoke phy_reset API before enabling PHY PCI: endpoint: Add support to allocate aligned buffers to be mapped in BARs PCI: dwc: Add const qualifier to struct dw_pcie_ep_ops PCI: dwc: Fix dw_pcie_ep_find_capability to return correct capability offset PCI: dwc: Add callbacks for accessing dbi2 address space PCI: keystone: Add support for PCIe EP in AM654x Platforms PCI: designware-ep: Configure RESBAR to advertise the smallest size PCI: designware-ep: Use aligned ATU window for raising MSI interrupts misc: pci_endpoint_test: Add support to test PCI EP in AM654x misc: pci_endpoint_test: Fix test_reg_bar to be updated in pci_endpoint_test .../bindings/pci/designware-pcie.txt | 7 +- .../devicetree/bindings/pci/pci-keystone.txt | 14 +- drivers/misc/pci_endpoint_test.c | 17 + drivers/pci/controller/dwc/Kconfig | 25 +- drivers/pci/controller/dwc/pci-dra7xx.c | 2 +- drivers/pci/controller/dwc/pci-keystone.c | 505 ++++++++++++++---- drivers/pci/controller/dwc/pcie-artpec6.c | 2 +- .../pci/controller/dwc/pcie-designware-ep.c | 55 +- .../pci/controller/dwc/pcie-designware-host.c | 19 - .../pci/controller/dwc/pcie-designware-plat.c | 2 +- drivers/pci/controller/dwc/pcie-designware.c | 52 ++ drivers/pci/controller/dwc/pcie-designware.h | 15 +- drivers/pci/endpoint/functions/pci-epf-test.c | 5 +- drivers/pci/endpoint/pci-epf-core.c | 10 +- include/linux/pci-epc.h | 2 + include/linux/pci-epf.h | 3 +- 16 files changed, 587 insertions(+), 148 deletions(-)
