Commit 8e093102 authored by Daniel Lezcano's avatar Daniel Lezcano

Revert "clockevents: Add a clkevt-of mechanism like clksrc-of"

After discussing it, this feature is dropped as it is not considered
adequate:

	https://patchwork.kernel.org/patch/9639317/

There is no user of this macro yet, so there is no impact on the drivers.

This reverts commit 376bc271.
