229 This option enables support for event stream generation based on
230 the ARM architected timer. It is used for waking up CPUs executing
231 the wfe instruction at a frequency represented as a power-of-2
232 divisor of the clock rate.
233 The main use of the event stream is wfe-based timeouts of userspace
234 locking implementations. It might also be useful for imposing timeout
235 on wfe to safeguard against any programming errors in case an expected
236 event is not generated.
237 This must be disabled for hardware validation purposes to detect any
238 hardware anomalies of missing events.

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