Merge branch 'remotes/lorenzo/pci/endpoint'
- Use memcpy_fromio()/memcpy_toio() instead of plain memcpy() in PCI endpoint framework (Wen Yang) - Add interface to discover supported endpoint features to replace a bitfield that wasn't flexible enough (Kishon Vijay Abraham I) - Implement the new supported-feature interface for designware-plat, dra7xx, rockchip, cadence (Kishon Vijay Abraham I) - Fix issues with 64-bit BAR in endpoints (Kishon Vijay Abraham I) - Add layerscape endpoint mode support (Xiaowei Bao) * remotes/lorenzo/pci/endpoint: misc: pci_endpoint_test: Add the layerscape EP device support PCI: layerscape: Add EP mode support arm64: dts: Add the PCIE EP node in dts dt-bindings: add DT binding for the layerscape PCIe controller with EP mode PCI: endpoint: Remove features member in struct pci_epc PCI: designware-plat: Remove setting epc->features in Designware plat EP driver PCI: rockchip: Remove pci_epf_linkup() from Rockchip EP driver PCI: cadence: Remove pci_epf_linkup() from Cadence EP driver PCI: pci-epf-test: Use pci_epc_get_features() to get EPC features PCI: pci-epf-test: Do not allocate next BARs memory if current BAR is 64Bit PCI: pci-epf-test: Remove setting epf_bar flags in function driver PCI: endpoint: Fix pci_epf_alloc_space() to set correct MEM TYPE flags PCI: endpoint: Add helper to get first unreserved BAR PCI: cadence: Populate ->get_features() cdns_pcie_epc_ops PCI: rockchip: Populate ->get_features() dw_pcie_ep_ops PCI: pci-dra7xx: Populate ->get_features() dw_pcie_ep_ops PCI: designware-plat: Populate ->get_features() dw_pcie_ep_ops PCI: dwc: Add ->get_features() callback function to dw_pcie_ep_ops PCI: endpoint: Add new pci_epc_ops to get EPC features PCI: endpoint: functions: Use memcpy_fromio()/memcpy_toio()
