From 17659d7de9e4905f8d06966c2354c87cdeb8b703 Mon Sep 17 00:00:00 2001 From: Graeme Russ Date: Fri, 15 Jul 2011 02:21:14 +0000 Subject: Timer: Remove reset_timer_masked() In some circumstances, reset_timer_masked() was called be timer_init() in order to perform architecture specific timer initialisation. In such cases, the required code in reset_timer_masked() has been moved into timer_init() --- arch/arm/cpu/arm926ejs/armada100/timer.c | 10 ++-------- arch/arm/cpu/arm926ejs/kirkwood/timer.c | 10 ++-------- arch/arm/cpu/arm926ejs/mb86r0x/timer.c | 14 +++----------- arch/arm/cpu/arm926ejs/mx25/timer.c | 9 --------- arch/arm/cpu/arm926ejs/mx27/timer.c | 9 --------- arch/arm/cpu/arm926ejs/orion5x/timer.c | 10 ++-------- arch/arm/cpu/arm926ejs/pantheon/timer.c | 10 ++-------- arch/arm/cpu/arm926ejs/spear/timer.c | 11 +++-------- 8 files changed, 14 insertions(+), 69 deletions(-) (limited to 'arch/arm/cpu/arm926ejs') diff --git a/arch/arm/cpu/arm926ejs/armada100/timer.c b/arch/arm/cpu/arm926ejs/armada100/timer.c index 86da0ce..82a6d7b 100644 --- a/arch/arm/cpu/arm926ejs/armada100/timer.c +++ b/arch/arm/cpu/arm926ejs/armada100/timer.c @@ -77,13 +77,6 @@ ulong read_timer(void) return(readl(&armd1timers->cvwr));
