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.
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).
