From eaad2db03cbbf734aa95f99eb93fb6309637dbca Mon Sep 17 00:00:00 2001 From: Andrew Victor Date: Sun, 21 Sep 2008 21:35:18 +0100 Subject: [ARM] 5264/2: [AT91] Suspend-to-RAM disables main oscillator This patch adds support for a low(er)-power suspend-to-RAM. In addition to the SDRAM being put into self-refresh mode, the Master Clock is set to the Slow-clock rate (32Khz) and PLLA & PLLB are disabled. Certain peripherals are therefore also disabled, and thus cannot be used as wakeup sources. This patch has been included in the AT91 patches in various forms since 2.6.19 and a number of people have worked or commented on it, most notably: Savin Zlobec (for the original AT91RM9200 support) Anti Sullin (for the SAM9260 version) David Brownell, etc. Signed-off-by: Andrew Victor Signed-off-by: Russell King --- arch/arm/mach-at91/Makefile | 1 + 1 file changed, 1 insertion(+) (limited to 'arch/arm/mach-at91/Makefile') diff --git a/arch/arm/mach-at91/Makefile b/arch/arm/mach-at91/Makefile index a95c49b..cca612d 100644 --- a/arch/arm/mach-at91/Makefile +++ b/arch/arm/mach-at91/Makefile @@ -65,6 +65,7 @@ obj-y += leds.o # Power Management obj-$(CONFIG_PM) += pm.o +obj-$(CONFIG_AT91_SLOW_CLOCK) += pm_slowclock.o ifeq ($(CONFIG_PM_DEBUG),y) CFLAGS_pm.o += -DDEBUG -- cgit v1.1
