ACPI and power management updates for 3.14-rc1
- 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. From Jiang Liu.
- New Win8 OSI blacklist entries from Takashi Iwai.
- Assorted ACPI fixes and cleanups from Al Stone, Emil Goode, Hanjun Guo,
Lan Tianyu, Masanari Iida, Oliver Neukum, Prarit Bhargava, Rashika Kheria,
Tang Chen, Zhang Rui.
- intel_pstate driver updates, including proper Baytrail support, from
Dirk Brandewie and intel_pstate documentation from Ramkumar Ramachandra.

Merge tag 'pm+acpi-3.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI and power management updates from Rafael Wysocki:
"As far as the number of commits goes, the top spot belongs to ACPI
this time with cpufreq in the second position and a handful of PM
core, PNP and cpuidle updates. 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.

cpufreq: exynos4x12: Use the common clock framework to set APLL clock rate
In the exynos4x12_set_apll() function, the APLL frequency is set with direct register manipulation. Such approach is not allowed in the common clock framework. The frequency is changed, but the corresponding clock value is not updated. This causes wrong frequency read from cpufreq's cpuinfo_cur_freq sysfs attribute. Also direct manipulation with PLL's S parameter has been removed. It is already done at PLL35xx code.

arm-soc: cleanups
A large number of cleanups, all over the platforms. This is dominated largely by the Samsung platforms (s3c, s5p, exynos) and a few of the others moving code out of arch/arm into more appropriate subsystems. The clocksource and irqchip drivers are now abstracted to the point where platforms that are already cleaned up do not need to even specify the driver they use, it can all get configured from the device tree as we do for normal device drivers. The clocksource changes basically touch every single platform in the process. We further clean up the use of platform specific header files here, with the goal of turning more of the platforms over to being "multiplatform" enabled, which implies that they cannot expose their headers to architecture independent code any more. It is expected that no functional changes are part of the cleanup. The overall reduction in total code lines is mostly the result of removing broken and obsolete code. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAUSUyKmCrR//JCVInAQIN8RAAnb/uPytmlMjn5yCksF4Mvb/FVbn/TVwz KRIGpCHOzyKK1q7pM8NRUVWfjW2SZqbXJFqx6zBGKSlDPvFTOhsLyyupU+Tnyu5W IX4eIUBwb+a6H7XDHw0X2YI8uHzi5RNLhne0A1QyDKcnuHs1LDAttXnJHaK4Ap6Y NN2YFt3l3ld7DXWXJtMsw5v8lC10aeIFGTvXefaPDAdeMLivmI57qEUMDXknNr7W Odz/Rc0/cw3BNBVl/zNHA0jw7FOjKAymCYYNUa4xDCJEr+JnIRTqizd0N/YIIC7x aA2xjJ3oKUFyF51yiJE6nFuTyJznhwtehc+uiMOSIkjrPLym52LEHmd7G5Yqlmjz oiei09qBb870q3lGxwfht9iaeIwYgQFYGfD0yW5QWArCO5pxhtCPLPH7YZNZtcQd ZJRSGGqT/ljBz3bm0K9OLESeeTTN7+Nxvtpiz/CD+Piegz0gWJzDYJRTzkJ3UWpA WTVhVQdWUeX2JrNkgM7Z3Tu8iXOe+LIEs7kVXGJZSREmIIZiRvR36UrODZtAkp9I 7YQ+srX/uaR832pgK0RrHK0zY0psU6MmIvhYxJZFbx7keiPA9eH6drb0x7tGqcUD FzEUzvcZvyqppndfBi+R60H/YKAhJDEXdwxzo6dyCpPQaW1T9GnzIqXuE1zin+Aw X7Y8YywMbHI= =DvgJ -----END PGP SIGNATURE----- Merge tag 'cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC cleanups from Arnd Bergmann: "A large number of cleanups, all over the platforms.
