So here is what I am planning, keeping in mind the next set of platform support which I am planning to send out (say FSD, ARTPEC-v8): 1: We will move samsung pci driver inside dwc/samsung/ 2: pci-samsung.c shall contain common APIs, helper functions, etc 3: Platform specific driver will have their own files such as pcie-exynos.c, pcie-fsd.c, pcie-artpec-v8.c Let me know what you think of this. I am not very keen on renaming Exynos SoC file as pcie-exyons5433.c as in future we may end up adding PCIe support for other Exynos which being in same family (Exynos Series) will be very similar in design. Custom ASIC (manufactured by Samsung Foundry) is primarily driven by various vendors and will have separate design in terms of integration of IPs in SoC and we need to have support for all such SoCs manufactured under Samsung umbrella.
