config DM_PCI_COMPAT
	bool "Enable compatible functions for PCI"
	help
	  Enable compatibility functions for PCI so that old code can be used
	  with CONFIG_PCI enabled. This should be used as an interim
	  measure when porting a board to use driver model for PCI. Once the
	  board is fully supported, this option should be disabled.
