Please follow the subject line convention:

  PCI: exynos: Rework to support Exynos5433 variant
  arm64: dts: exynos: Add WiFi/PCIe support to TM2(e) boards
  dt-bindings: PCI: exynos: Drop samsung,exynos5440-pcie binding
  dt-bindings: PCI: exynos: Add samsung,exynos-pcie binding
  dt-bindings: phy: exynos: Add samsung,exynos-pcie-phy binding

You can save this trouble by running "git log --oneline" on the file
(or directory, for new files) and copying the style.
