Power management for s3c64XX and s3c24XX is enabled by default and for other platform depends on S5P_PM. This patch also fixes the following compilation error's when compiling a platform like exynos5440 which does not select pm stuffs. arch/arm/mach-exynos/built-in.o: In function `__virt_to_phys': linux/arch/arm/include/asm/memory.h:175: undefined reference to `s3c_cpu_resume' linux/arch/arm/include/asm/memory.h:175: undefined reference to `s3c_cpu_resume' linux/arch/arm/include/asm/memory.h:175: undefined reference to `s3c_cpu_resume' linux/arch/arm/include/asm/memory.h:175: undefined reference to `s3c_cpu_resume' arch/arm/mach-exynos/built-in.o: In function `exynos5_init_irq': linux/arch/arm/mach-exynos/common.c:492: undefined reference to `s3c_irq_wake' linux/arch/arm/mach-exynos/common.c:492: undefined reference to `s3c_irq_wake' arch/arm/mach-exynos/built-in.o: In function `exynos4_init_irq': linux/arch/arm/mach-exynos/common.c:476: undefined reference to `s3c_irq_wake' linux/arch/arm/mach-exynos/common.c:476: undefined reference to `s3c_irq_wake' arch/arm/plat-samsung/built-in.o: In function `s3c_irqext_wake': linux/arch/arm/plat-samsung/pm.c:144: undefined reference to `s3c_irqwake_eintallow' linux/arch/arm/plat-samsung/pm.c:144: undefined reference to `s3c_irqwake_eintallow' arch/arm/plat-samsung/built-in.o: In function `s3c_pm_enter': linux/arch/arm/plat-samsung/pm.c:263: undefined reference to `s3c_irqwake_intallow' linux/arch/arm/plat-samsung/pm.c:263: undefined reference to `s3c_irqwake_intallow' linux/arch/arm/plat-samsung/pm.c:264: undefined reference to `s3c_irqwake_eintallow' linux/arch/arm/plat-samsung/pm.c:264: undefined reference to `s3c_irqwake_eintallow' linux/arch/arm/plat-samsung/pm.c:275: undefined reference to `s3c_pm_save_core' linux/arch/arm/plat-samsung/pm.c:279: undefined reference to `s3c_pm_configure_extint' linux/arch/arm/plat-samsung/pm.c:310: undefined reference to `s3c_pm_restore_core' make: *** [vmlinux] Error 1 Signed-off-by: Amit Daniel Kachhap --- arch/arm/mach-exynos/Makefile | 2 +- arch/arm/mach-exynos/common.c | 2 +- arch/arm/mach-exynos/common.h | 1 - arch/arm/mach-exynos/cpuidle.c | 1 + arch/arm/plat-samsung/Kconfig | 7 +++++++ arch/arm/plat-samsung/Makefile | 3 +-- arch/arm/plat-samsung/include/plat/pm.h | 8 ++++---- 7 files changed, 15 insertions(+), 9 deletions(-) diff --git a/arch/arm/mach-exynos/Makefile b/arch/arm/mach-exynos/Makefile index 9811f87..3fa277a 100644 --- a/arch/arm/mach-exynos/Makefile +++ b/arch/arm/mach-exynos/Makefile @@ -14,7 +14,7 @@ obj- := obj-$(CONFIG_ARCH_EXYNOS) += common.o -obj-$(CONFIG_PM) += pm.o +obj-$(CONFIG_S5P_PM) += pm.o obj-$(CONFIG_PM_GENERIC_DOMAINS) += pm_domains.o obj-$(CONFIG_CPU_IDLE) += cpuidle.o diff --git a/arch/arm/mach-exynos/common.c b/arch/arm/mach-exynos/common.c index 9834357..d2b4f54 100644 --- a/arch/arm/mach-exynos/common.c +++ b/arch/arm/mach-exynos/common.c @@ -799,7 +799,7 @@ static struct irq_chip exynos_irq_eint = { .irq_mask_ack = exynos_irq_eint_maskack, .irq_ack = exynos_irq_eint_ack, .irq_set_type = exynos_irq_eint_set_type, -#ifdef CONFIG_PM +#ifdef CONFIG_S5P_PM .irq_set_wake = s3c_irqext_wake, #endif };
