ARM: EXYNOS: Fix build with PM_SLEEP=n and ARM_EXYNOS_CPUIDLE=y
Fix building of exynos_defconfig with CONFIG_PM_SLEEP disabled and
CONFIG_ARM_EXYNOS_CPUIDLE enabled by:
* adding EXYNOS_CPU_SUSPEND config option
* always building sleep.o
* building pm.o if EXYNOS_CPU_SUSPEND is enabled
* moving suspend specific code from pm.c to suspend.c
* enabling pm-common.o build also for EXYNOS_CPU_SUSPEND option
[ Please note that there are no changes in the code moved from pm.c
to suspend.c except making few functions non-static and cleaning
up includes. ]
Also while at it update Copyright dates.
The build error messages:
drivers/built-in.o: In function `exynos_enter_core0_aftr':
/home/bzolnier/linux/drivers/cpuidle/cpuidle-exynos.c:36: undefined reference to `cpu_suspend'
arch/arm/mach-exynos/built-in.o:(.data+0x74): undefined reference to `exynos_enter_aftr'
make: *** [vmlinux] Error 1
This patch has been tested on Exynos4210 based Origen board.
