Allow DesignWare EPs that doesn't have linkup notification signal to work with pcitest. Update the binding documentation accordingly. Signed-off-by: Gustavo Pimentel Acked-by: Kishon Vijay Abraham I --- Change v2->v3: - Added second entry in pci_epf_test_ids structure. - Remove test_reg_bar field assignment on second entry. Changes v3->v4: - Nothing changed, just to follow the patch set version. Changes v4->v5: - Changed pci_epf_test_cfg2 to pci_epf_test_designware. Changes v5->v6: - Changed name field from pci_epf_test_designware to pci_epf_test_dw. Changes v6->v7: - Changed variable name from data_cfg2 to data_linkup_notifier_disabled. Changes v7->v8: - Patch description rework for an imperative verbal mode.
