This patch enables the selection of samsung pm related stuffs when SAMSUNG_PM config is enabled and not just when generic PM config is enabled. 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 <amit.daniel@samsung.com> --- 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(-)
