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.

When running under a TEE, the suspend mode must be requested to be set
at TEE level. When enable, this option will use secure monitor calls
to set the suspend level. PSCI is then used to enter suspend.
