From 3169663ac5902f2228ea0eb8cc34eb52cbd4b283 Mon Sep 17 00:00:00 2001 From: Russell King Date: Wed, 6 Jun 2012 11:42:36 +0100 Subject: ARM: sa11x0/pxa: convert OS timer registers to IOMEM Make the OS timer registers have IOMEM like properities so they can be passed to readl_relaxed/writel_relaxed() et.al. rather than being straight volatile dereferences. Add linux/io.h includes where required. linux/io.h includes added to arch/arm/mach-sa1100/cpu-sa1100.c, arch/arm/mach-sa1100/jornada720_ssp.c, arch/arm/mach-sa1100/leds-lart.c drivers/input/touchscreen/jornada720_ts.c, drivers/pcmcia/sa1100_shannon.c from Arnd. This fixes these warnings: arch/arm/mach-sa1100/time.c: In function 'sa1100_timer_init': arch/arm/mach-sa1100/time.c:104: warning: passing argument 1 of 'clocksource_mmio_init' discards qualifiers from pointer target type arch/arm/mach-pxa/time.c: In function 'pxa_timer_init': arch/arm/mach-pxa/time.c:126: warning: passing argument 1 of 'clocksource_mmio_init' discards qualifiers from pointer target type Signed-off-by: Arnd Bergmann Signed-off-by: Russell King --- arch/arm/mach-pxa/reset.c | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) (limited to 'arch/arm/mach-pxa/reset.c') diff --git a/arch/arm/mach-pxa/reset.c b/arch/arm/mach-pxa/reset.c index b4528899ef08..3fab583755d4 100644 --- a/arch/arm/mach-pxa/reset.c +++ b/arch/arm/mach-pxa/reset.c @@ -77,9 +77,10 @@ static void do_gpio_reset(void) static void do_hw_reset(void) { /* Initialize the watchdog and let it fire */ - OWER = OWER_WME; - OSSR = OSSR_M3; - OSMR3 = OSCR + 368640; /* ... in 100 ms */ + writel_relaxed(OWER_WME, OWER); + writel_relaxed(OSSR_M3, OSSR); + /* ... in 100 ms */ + writel_relaxed(readl_relaxed(OSCR) + 368640, OSMR3); } void pxa_restart(char mode, const char *cmd) -- cgit v1.2.3
