  84          This is a new clocksource driver for the PWM timer found in
  85          Samsung S3C, S5P and Exynos SoCs, replacing an earlier driver
  86          for all devicetree enabled platforms. This driver will be
  87          needed only on systems that do not have the Exynos MCT available.
