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
