  clocksource/drivers/timer-ti-dm: Select TIMER_OF (2021-10-21 14:18:53

Please note there is a shared branch with the arm tree armv8.6_arch_timer

The reason of the sharing is described in the merge commit.

- Fix redefined macro in the arc timer ()

- Big cleanup for ARM arch timer clocksource in order to set the scene
  for ARMv8.6 and provide support for higher frequencies with longer
  roll up (Marc Zyngier)

- Make arch dependant the Exynos MCT and Samsung PWM timers (Krzysztof

- Select the TIMER_OF option for the timer TI DM (Kees Cook)
