13 | /* Various drivers are still using the constant of CLOCK_TICK_RATE, for |
14 | * those drivers to at least work, the definition is provided here. | |
15 | * | |
16 | * NOTE: this is no longer accurate when multiple processors and boards | |
17 | * are selected, newer drivers should not depend on this any more. Use | |
18 | * either the clocksource/clockevent or get this at run-time by calling | |
19 | * get_clock_tick_rate() (as defined in generic.c). | |
