- help
- 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.

- default 0
- range 0 1
- help
- 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
- interval timing.
