From 6769717d5d51596618f6b143008d8ace11ec8a69 Mon Sep 17 00:00:00 2001 From: Eric Miao Date: Thu, 18 Dec 2008 11:10:32 +0800 Subject: [ARM] rtc-sa1100: don't assume CLOCK_TICK_RATE to be a constant As Nicolas and Russell pointed out, CLOCK_TICK_RATE is no more a constant on PXA when multiple processors and platforms are selected, change TIMER_FREQ in rtc-sa1100.c into a variable. Since the code to decide the clock tick rate is re-used from timer.c, introduce a common get_clock_tick_rate() for this.
