Pull thermal management updates from Zhang Rui:
"This time, the biggest change is the work of representing hardware
thermal properties in device tree infrastructure.
This work includes the introduction of a device tree bindings for
describing the hardware thermal behavior and limits, and also a parser
to read and interpret the data, and build thermal zones and thermal
binding parameters. It also contains three examples on how to use the
new representation on sensor devices, using three different drivers to
accomplish it. One driver is in thermal subsystem, the TI SoC
thermal, and the other two drivers are in hwmon subsystem.
Actually, this would be the first step of the complete work because we
still need to check other potential drivers to be converted and then
validate the proposed API. But the reason why I include it in this
pull request is that, first, this change does not hurt any others
without using this approach, second, the principle and concept of this
change would not break after converting the remaining drivers. BTW,
as you can see, there are several points in this change that do not
belong to thermal subsystem. Because it has been suggested by Guenter
R that in such cases, it is recommended to send the complete series
via one single subsystem.
Specifics:
- representing hardware thermal properties in device tree
infrastructure
- fix a regression that the imx thermal driver breaks system suspend.
- introduce ACPI INT3403 thermal driver to retrieve temperature data
from the INT3403 ACPI device object present on some systems.
- introduce debug statement for thermal core and step_wise governor.
- assorted fixes and cleanups for thermal core, cpu cooling, exynos
thrmal, intel powerclamp and imx thermal driver"

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.
- 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,

Pull clk framework changes from Mike Turquette:
"The first half of the clk framework pull request is made up almost
entirely of new platform/driver support. There are some conversions
of existing drivers to the common-clock Device Tree binding, and a few
non-critical fixes to the framework.
Due to an entirely unnecessary cyclical dependency with the arm-soc
tree this pull request is broken into two pieces. The second piece
will be sent out after arm-soc sends you the pull request that merged
in core support for the HiSilicon 3620 platform. That same pull
request from arm-soc depends on this pull request to merge in those
HiSilicon bits without causing build failures"

Pull ARM driver updates from Olof Johansson:
"Updates of SoC-near drivers and other driver updates that makes more
sense to take through our tree.
The largest part of this is a conversion of device registration for
some renesas shmobile/sh devices over to use resources. This has
required coordination with the corresponding arch/sh changes, and
we've agreed to merge the arch/sh changes through our tree.
Added in this branch is support for Trusted Foundations secure
firmware, which is what is used on many of the commercial Nvidia Tegra
products that are in the market, including the Nvidia Shield. The
code is local to arch/arm at this time since it's uncertain whether it
will be shared with arm64 longer-term, if needed we will refactor
later.

This patch is used to add support for ms card. The main difference
between ms card and mspro card is long data transfer mode. mspro card
can use auto mode DMA for long data transfer, but ms can not use this
mode, it should use normal mode DMA.
The memstick core added support for ms card, but the original driver will
make ms card fail at initialization, because it uses auto mode DMA. This
patch makes the ms card work properly.

Add support for SMBus-only adapters (e.g. i2c-piix4). The driver has
implemented only support for I2C adapters which implement the
I2C_FUNC_SMBUS_I2C_BLOCK functionality before.
With this patch it is possible to load and use the RTC driver with I2C and
SMBUS adapters like the rtc-ds1307 does.

The current MAX8907 driver has two issues related to weekday value
handling:
1)
The HW WEEKDAY register has range 0..6 rather than 1..7 as documented.
Note that I validated the actual HW range by observing the HW register
roll from 6->0 rather than 6->7->1 as would otherwise be expected.
This matches Linux's tm_wday range of 0..6.
When the CMOS RAM content is lost, the date returned from the device is
2007-01-01 00:00:00, which is a Monday. The WEEKDAY register reads 1 in
this case. This matches the numbering in Linux's tm_wday field.
Hence we should write Linux's tm_wday value to the register without
modifying it. Hence, remove the +1/-1 calculations for WEEKDAY/tm_wday.
2)
There's no need to make alarms match on the WEEKDAY register, since the
other fields together uniquely define the alarm date/time. Ignoring the
WEEKDAY value in the match isolates the driver from any incorrect value in
the current time copy of the WEEKDAY register.
Each change individually, or both together, solves an issue that I
observed; "hwclock -r" would time out waiting for its alarm to fire if the
CMOS RAM content had been lost, and hence the WEEKDAY register value
mismatched what the driver expected it to be. "hwclock -w" would solve
this by over-writing the HW default WEEKDAY register value with what the
driver expected.

Assign RTC device IDs based on device tree /aliases entries if present,
falling back to the existing numbering scheme if there is no /aliases
entry (which includes when the system isn't booted using DT), or there is
a numbering conflict.
This is useful in systems with multiple RTC devices, to ensure that the
best RTC device is selected as /dev/rtc0, which provides the overall
system time.
For example, Tegra has an on-SoC RTC that is not battery backed, typically
coupled with an off-SoC RTC that is battery backed. Only the latter is
useful for populating the system time, yet the former is useful e.g. for
wakeup timing, since the time is not lost when the system is sleeps.

On ARAnyM (emulating an Atari Falcon, which doesn't have an RTC IRQ, as

only), rtc-cmos doesn't work well:
- The date is of by 32 years (2045 instead of 2013):
rtc_cmos rtc_cmos: setting system clock to 2045-12-02 10:56:17 UTC

- The hwclock utility doesn't work:
hwclock: ioctl() to /dev/rtc to turn on update interrupts failed
unexpectedly, errno=5: Input/output error.
As rtc-generic works fine for the RTC part, and nvram works for the NVRAM
part, we'll continue on using that.
