ARM: fix footbridge clockevent device
commit 4ff859fe1dc0da0f87bbdfff78f527898878fa4a upstream. The clockevents code was being told that the footbridge clock event device ticks at 16x the rate which it actually does. This leads to timekeeping problems since it allows the clocksource to wrap before the kernel notices. Fix this by using the correct clock. Fixes: 4e8d76373c9fd ("ARM: footbridge: convert to clockevents/clocksource") Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> [bwh: Backported to 3.2: fold in the relevant parts of commit 838a2ae80a6a ('ARM: use clockevents_config_and_register() where possible')] Signed-off-by: Ben Hutchings <ben@decadent.org.uk>
