- * These timers work in a rather peculiar fashion. Most clock counters
- * run to 0 (as, e.g., on the VAX, where the ICR counts up to 0 from a
- * large unsigned number). On the Sun-4c, it counts up to a limit. But
- * for some reason, when it reaches the limit, it resets to 1, not 0.
- * Thus, if the limit is set to 4, the counter counts like this:
- *
- * 1, 2, 3, 1, 2, 3, ...
- *
- * and if we want to divide by N we must set the limit register to N+1.
- *
- * Sun-4u counters/timer are similar but:
- *
- * - the registers have been shuffled around once again. We need
- * to use offsets from the 3 addresses the ROM provides us.
- * - The counters are 29 bits wide with 1us accuracy.
- * - You can make them do funky things with the limit register
- * - They have standard 64-bit SBus control registers.
- *
- * There is a problem on the Ultra5 and Ultra10. As the PCI controller
- * doesn't include the timer, there are no `counter-timer' nodes here
- * and so we must use %tick.
