I think you're talking about a PCI host bridge driver. It would definitely be nice to move toward a generic, shared driver. Host bridge drivers are responsible for enumerating the PCI hierarchy below the bridge. Enumeration is not really PCIe-specific, so I wouldn't put it in drivers/pci/pcie. > Is using readl/writel IO functions in this driver the best option > which we can have? > Or is there any other recommendation? I'm not really a driver person, but if you're writing a new driver, wouldn't you use the iomap interfaces (ioremap(), ioread32(), etc) rather than readl()? > Also just want to check if it is correct to use pcie device_type.
