Subject: [PATCH 00/16] Refactor Exynos PCIe driver to make it generic

Currently pci-exynos is being used as a PCIe driver for Exynos5433
only. 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
