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. This patchset is based on the following branch: git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux.git pci-more-dwc-cleanup Best regards, Marek Szyprowski Changelog: v3: - rebased onto "[00/13] PCI: dwc: Another round of clean-ups" patchset: https://patchwork.kernel.org/project/linux-samsung-soc/cover/20201028204646.356535-1-robh@xxxxxxxxxx/ - fixed issues pointed by Rob in the driver logic: * removed DBI_RO_WR_EN register poking * made driver a standard module - fixed section mismatch issue - added "num-viewport = <3>" property to dts and bindings to fix warning v2: https://lore.kernel.org/linux-samsung-soc/20201023075744.26200-1-m.szyprowski@xxxxxxxxxxx/ - fixed issues in dt-bindings pointed by Krzysztof and Rob v1: https://lore.kernel.org/linux-samsung-soc/20201019094715.15343-1-m.szyprowski@xxxxxxxxxxx/ - initial version of this resurrected patchset Patch summary: Jaehoon Chung (3): phy: samsung: phy-exynos-pcie: rework driver to support Exynos5433 PCIe PHY pci: dwc: pci-exynos: rework the driver to support Exynos5433 variant arm64: dts: exynos: add the WiFi/PCIe support to TM2(e) boards Marek Szyprowski (3): dt-bindings: pci: drop samsung,exynos5440-pcie binding dt-bindings: pci: add the samsung,exynos-pcie binding dt-bindings: phy: add the samsung,exynos-pcie-phy binding .../bindings/pci/samsung,exynos-pcie.yaml | 119 ++++++ .../bindings/pci/samsung,exynos5440-pcie.txt | 58 --- .../bindings/phy/samsung,exynos-pcie-phy.yaml | 51 +++ .../boot/dts/exynos/exynos5433-pinctrl.dtsi | 2 +- .../dts/exynos/exynos5433-tm2-common.dtsi | 24 +- arch/arm64/boot/dts/exynos/exynos5433.dtsi | 36 ++ drivers/pci/controller/dwc/Kconfig | 10 +- drivers/pci/controller/dwc/pci-exynos.c | 353 +++++++----------- drivers/pci/quirks.c | 1 + drivers/phy/samsung/phy-exynos-pcie.c | 304 ++++++--------- 10 files changed, 489 insertions(+), 469 deletions(-) create mode 100644 Documentation/devicetree/bindings/pci/samsung,exynos-pcie.yaml delete mode 100644 Documentation/devicetree/bindings/pci/samsung,exynos5440-pcie.txt create mode 100644 Documentation/devicetree/bindings/phy/samsung,exynos-pcie-phy.yaml -- 2.17.1
