16 | * We're configured to use a specific TC block, one that's not hooked | ||
17 | * up to external hardware, to provide a time solution: | ||
18 | * | ||
19 | * - Two channels combine to create a free-running 32 bit counter | ||
20 | * with a base rate of 5+ MHz, packaged as a clocksource (with | ||
21 | * resolution better than 200 nsec). | ||
22 | * | ||
23 | * - The third channel may be used to provide a 16-bit clockevent | ||
24 | * source, used in either periodic or oneshot mode. This runs | ||
25 | * at 32 KiHZ, and can handle delays of up to two seconds. | ||
26 | * | ||
27 | * A boot clocksource and clockevent source are also currently needed, | ||
28 | * unless the relevant platforms (ARM/AT91, AVR32/AT32) are changed so | ||
29 | * this code can be used when init_timers() is called, well before most | ||
30 | * devices are set up. (Some low end AT91 parts, which can run uClinux, | ||
31 | * have only the timers in one TC block... they currently don't support | ||
32 | * the tclib code, because of that initialization issue.) | ||
33 | * | ||
34 | * REVISIT behavior during system suspend states... we should disable | ||
35 | * all clocks and save the power. Easily done for clockevent devices, | ||
36 | * but clocksources won't necessarily get the needed notifications. | ||
37 | * For deeper system sleep states, this will be mandatory... | ||
