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