Thomas Abraham authored
A seperate bus_type instance is not required for EXYNOS5. The existing bus_type instance used with EXYNOS4 is sufficient for both EXYNOS4 and EXYNOS5. This also solves issue of uninitialized usage of exynos4_subsys in EXYNOS4 power management code that is reused for EXYNOS5 also. In addition to that, the existing exynos4_subsys bus_type is renamed to exynos_subsys to indicate that it is reused on both EXYNOS4 and EXYNOS5 platforms. Signed-off-by:

Commit 069d4e74 ("ARM: EXYNOS4: Remove clock event timers using ARM private timers") removed support for local timers and forced to use MCT as event source. However MCT is not operating properly on early revision of EXYNOS4 SoCs. All UniversalC210 boards are based on it, so that commit broke support for it. This patch provides a workaround that enables UniversalC210 boards to boot again. s5p-timer is used as an event source, it works only for non-SMP builds. Signed-off-by:

Fix SMP TWD boot regression on sh73a0 based platforms caused by: 4200b16d ARM: shmobile: convert to twd_local_timer_register() interface After the merge of the above commit it has been impossible to boot sh73a0 based SoCs with SMP enabled and CONFIG_HAVE_ARM_TWD=y. The kernel crashes at smp_init_cpus() timing which is before the console has been initialized, so to the user this looks like a kernel lock up without any particular error message. This patch fixes the regression on sh73a0 by moving the TWD registration code from smp_init_cpus() to sys_timer->init() time. This patch removed shmobile_twd_init() which is no longer needed Signed-off-by:
