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.
