* ARM: EXYNOS: Disable cpuidle for exynos5440Daniel Lezcano2014-05-25
| | | | | | | | | | | | | | | | | There is no point to register the cpuidle driver for the 5440 as it has only one WFI state which is the default idle function when the cpuidle driver is disabled. By disabling cpuidle we prevent to enter to the governor computation for nothing, thus saving a lot of processing time. The only drawback is the statistic via sysfs on this state which is lost but it is meaningless and it could be retrieved from the ftrace easily.

They are fixes and cleanups mostly, as usual, with a couple of new features in the mix. The most visible change is probably that we will create struct acpi_device objects (visible in sysfs) for all devices represented in the ACPI tables regardless of their status and there will be a new sysfs attribute under those objects allowing user space to check that status via _STA. Consequently, ACPI device eject or generally hot-removal will not delete those objects, unless the table containing the corresponding namespace nodes is unloaded, which is extremely rare. Also ACPI container hotplug will be handled quite a bit differently and cpufreq will support CPU boost ("turbo") generically and not only in the acpi-cpufreq driver. Specifics: - ACPI core changes to make it create a struct acpi_device object for every device represented in the ACPI tables during all namespace scans regardless of the current status of that device. In accordance with this, ACPI hotplug operations will not delete those objects, unless the underlying ACPI tables go away. - On top of the above, new sysfs attribute for ACPI device objects allowing user space to check device status by triggering the execution of _STA for its ACPI object. From Srinivas Pandruvada. - ACPI core hotplug changes reducing code duplication, integrating the PCI root hotplug with the core and reworking container hotplug. - ACPI core simplifications making it use ACPI_COMPANION() in the code "glueing" ACPI device objects to "physical" devices. - ACPICA update to upstream version 20131218. This adds support for the DBG2 and PCCT tables to ACPICA, fixes some bugs and improves debug facilities. From Bob Moore, Lv Zheng and Betty Dall. - Init code change to carry out the early ACPI initialization earlier. That should allow us to use ACPI during the timekeeping initialization and possibly to simplify the EFI initialization too. From Chun-Yi Lee. - Clenups of the inclusions of ACPI headers in many places all over from Lv Zheng and Rashika Kheria (work in progress). - New helper for ACPI _DSM execution and rework of the code in drivers that uses _DSM to execute it via the new helper.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The EXYNOS cpuidle driver code assumes that cpuidle core will handle dev->state_count smaller than drv->state_count but currently this is untrue (dev->state_count is used only for handling cpuidle state sysfs entries and drv->state_count is used for all other cases) and will not be fixed in the future as dev->state_count is planned to be removed. Fix the issue by checking for the max supported idle state in AFTR state's ->enter handler (exynos4_enter_lowpower()) and entering AFTR mode only when cores other than CPU0 are offline.

* ARM: EXYNOS: Add ARCH_EXYNOS and reorganize arch/arm/mach-exynosKukjin Kim2011-11-06
The arch/arm/mach-exynos4 directory (CONFIG_ARCH_EXYNOS4) has made for plaforms based on EXYNOS4 SoCs. But since upcoming Samsung's SoCs such as EXYNOS5 (ARM Cortex A15) can reuse most codes in current mach-exynos4, one mach-exynos directory will be used for them. This patch changes to CONFIG_ARCH_EXYNOS (arch/arm/mach-exynos) but keeps original CONFIG_ARCH_EXYNOS4 in mach-exynos/Kconfig to avoid changing in driver side.
