From: Amit Daniel Kachhap Date: Wed, 24 Jul 2013 05:06:13 +0000 (+0900) Subject: ARM: SAMSUNG: Add SAMSUNG_PM config option to select pm X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=89693016e372983d720c186c0d00b29414b58804;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git ARM: SAMSUNG: Add SAMSUNG_PM config option to select pm 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 Signed-off-by: Kukjin Kim --- diff --git a/arch/arm/mach-exynos/Makefile b/arch/arm/mach-exynos/Makefile index e970a7a4e278..53696154aead 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.h b/arch/arm/mach-exynos/common.h index 3e156bcddcb4..972490fc09d6 100644 --- a/arch/arm/mach-exynos/common.h +++ b/arch/arm/mach-exynos/common.h @@ -97,6 +97,5 @@ struct exynos_pmu_conf { };
