94 help
95 This option enables support for event stream generation based on
96 the ARM architected timer. It is used for waking up CPUs executing
97 the wfe instruction at a frequency represented as a power-of-2
98 divisor of the clock rate.
99 The main use of the event stream is wfe-based timeouts of userspace
100 locking implementations. It might also be useful for imposing timeout
101 on wfe to safeguard against any programming errors in case an expected
102 event is not generated.
103 This must be disabled for hardware validation purposes to detect any
104 hardware anomalies of missing events.

133 Samsung S3C, S5P and Exynos SoCs, replacing an earlier driver
134 for all devicetree enabled platforms. This driver will be
135 needed only on systems that do not have the Exynos MCT available.
