+ Select this to get a high precision clocksource based on a
+ TC block with a 5+ MHz base clock rate. Two timer channels
+ are combined to make a single 32-bit timer.
+
+ When GENERIC_CLOCKEVENTS is defined, the third timer channel
+ may be used as a clock event device supporting oneshot mode
+ (delays of up to two seconds) based on the 32 KiHz clock.

+ Some chips provide more than one TC block, so you have the
+ choice of which one to use for the clock framework. The other
+ TC can be used for other purposes, such as PWM generation and
