Merge branch 'pci/endpoint-test'
- Clear pci-epf-test dma_chan_rx, not dma_chan_tx, after freeing dma_chan_rx (Mohamed Khalfella) - Correct the DMA MEMCPY test so it doesn't fail if the Endpoint supports both DMA_PRIVATE and DMA_MEMCPY (Manivannan Sadhasivam) - Add pci-epf-test and pci_endpoint_test support for capabilities (Niklas Cassel) - Add Endpoint test for consecutive BARs (Niklas Cassel) - Remove redundant comparison from Endpoint BAR test because a > 1MB BAR can always be exactly covered by iterating with a 1MB buffer (Hans Zhang) - Correct the PCI Endpoint test IOCTL return value (Manivannan Sadhasivam) - Move PCI Endpoint tests from tools/pci to Kselftests (Manivannan Sadhasivam) - Convert PCI Endpoint tests to the Kselftest framework (Manivannan Sadhasivam) * pci/endpoint-test: selftests: pci_endpoint: Migrate to Kselftest framework selftests: Move PCI Endpoint tests from tools/pci to Kselftests misc: pci_endpoint_test: Fix IOCTL return value misc: pci_endpoint_test: Remove redundant 'remainder' test misc: pci_endpoint_test: Add consecutive BAR test misc: pci_endpoint_test: Add support for capabilities PCI: endpoint: pci-epf-test: Add support for capabilities PCI: endpoint: pci-epf-test: Fix check for DMA MEMCPY test PCI: endpoint: pci-epf-test: Set dma_chan_rx pointer to NULL on error

Testcase 16 (pci_ep_data_transfer.dma.COPY_TEST) will fail for most of the DMA
201+
capable endpoint controllers due to the absence of the MEMCPY over DMA. For such
202+
controllers, it is advisable to skip this testcase using this
203+
command::
204+
205+
# pci_endpoint_test -f pci_ep_bar -f pci_ep_basic -v memcpy -T COPY_TEST -v dma
