++ * We're configured to use a specific TC block, one that's not hooked

++ * with a base rate of 5+ MHz, packaged as a clocksource (with
++ * resolution better than 200 nsec).
++ *
++ * - The third channel may be used to provide a 16-bit clockevent
++ * source, used in either periodic or oneshot mode. This runs
++ * at 32 KiHZ, and can handle delays of up to two seconds.
++ *
++ * A boot clocksource and clockevent source are also currently needed,
++ * unless the relevant platforms (ARM/AT91, AVR32/AT32) are changed so
++ * this code can be used when init_timers() is called, well before most
++ * devices are set up. (Some low end AT91 parts, which can run uClinux,
++ * have only the timers in one TC block... they currently don't support
++ * the tclib code, because of that initialization issue.)
++ *
++ * REVISIT behavior during system suspend states... we should disable
++ * all clocks and save the power. Easily done for clockevent devices,
++ * but clocksources won't necessarily get the needed notifications.
