Merge branch 'remotes/lorenzo/pci/endpoint'

Browse Source 
- 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()
