This patch set refactors the driver to make it extensible to other Samsung manufactured SoCs having DWC PCIe controllers. The major change points are: - Renaming all common functions/structures to use "samsung" instead of "exynos". Make common probe/remove/suspend/resume - Making clock/regulator get/enable/disable generic - Adding private struct to hold platform specific function ops Shradha Todi (16): dt-bindings: PCI: Rename Exynos PCIe binding to Samsung PCIe PCI: exynos: Rename Exynos PCIe driver to Samsung PCIe PCI: samsung: Change macro names to exynos specific PCI: samsung: Use clock bulk API to get clocks dt-bindings: PCI: Rename the term elbi to appl arm64: dts: exynos: Rename the term elbi to appl PCI: samsung: Rename the term elbi to appl PCI: samsung: Rename exynos_pcie to samsung_pcie PCI: samsung: Make common appl readl/writel functions dt-bindings: PCI: Add phy-names as required property arm64: dts: exynos: Add phy-names as DT property PCI: samsung: Get PHY using non-DT version PCI: samsung: Rename common functions to samsung PCI: samsung: Add platform device private data PCI: samsung: Add structure to hold resource operations PCI: samsung: Make handling of regulators generic ...ung,exynos-pcie.yaml => samsung,pcie.yaml} | 15 +- MAINTAINERS | 4 +- arch/arm64/boot/dts/exynos/exynos5433.dtsi | 3 +- drivers/pci/controller/dwc/Kconfig | 6 +- drivers/pci/controller/dwc/Makefile | 2 +- drivers/pci/controller/dwc/pci-samsung.c | 508 ++++++++++++++++++ 6 files changed, 526 insertions(+), 12 deletions(-) rename Documentation/devicetree/bindings/pci/{samsung,exynos-pcie.yaml => samsung,pcie.yaml} (89%) create mode 100644 drivers/pci/controller/dwc/pci-samsung.c
