Dear All, This patchset is a resurrection of the DW PCIe support for the Exynos5433 SoCs posted long time ago here: https://lkml.org/lkml/2016/12/26/6 and later here: https://lkml.org/lkml/2017/12/21/296 . In meantime the support for the Exynos5440 SoCs has been completely dropped from mainline kernel, as those SoCs never reached the market. The PCIe driver for Exynos5440 variant however has not been removed yet. This patchset simply reworks it to support the Exynos5433 variant. The lack of the need to support both variants significantly simplifies the driver code.
