	  Select this to get a clocksource based on the Atmel Periodic Interval
	  Timer. It has a relatively low resolution and the TC Block clocksource
	  should be preferred.

	  Select this to get a high precision clocksource based on a
	  TC block with a 5+ MHz base clock rate.
	  On platforms with 16-bit counters, two timer channels are combined
	  to make a single 32-bit timer.
	  It can also be used as a clock event device supporting oneshot mode.
