This adds support for the Linear Technology LTC2990 I2C System Monitor.
The LTC2990 supports a combination of voltage, current and temperature
monitoring. This driver currently only supports reading two currents
by measuring two differential voltages across series resistors, in
addition to the Vcc supply voltage and internal temperature.This is sufficient to support the Topic Miami SOM which uses this chip
to monitor the currents flowing into the FPGA and the CPU parts.Signed-off-by: Mike Looijmans

Pull ARM SoC driver updates from Olof Johansson:
"As we've enabled multiplatform kernels on ARM, and greatly done away
with the contents under arch/arm/mach-*, there's still need for
SoC-related drivers to go somewhere.Many of them go in through other driver trees, but we still have
drivers/soc to hold some of the "doesn't fit anywhere" lowlevel code
that might be shared between ARM and ARM64 (or just in general makes
sense to not have under the architecture directory).This branch contains mostly such code:
- Drivers for qualcomm SoCs for SMEM, SMD and SMD-RPM, used to
communicate with power management blocks on these SoCs for use by
clock, regulator and bus frequency drivers.- Allwinner Reduced Serial Bus driver, again used to communicate with
PMICs.- Drivers for ARM's SCPI (System Control Processor). Not to be
confused with PSCI (Power State Coordination Interface). SCPI is
used to communicate with the assistant embedded cores doing power
management, and we have yet to see how many of them will implement
this for their hardware vs abstracting in other ways (or not at all
like in the past).- To make confusion between SCPI and PSCI more likely, this release
also includes an update of PSCI to interface version 1.0.- Rockchip support for power domains.

This patch splits CONFIG_I8K compile option to SENSORS_DELL_SMM and CONFIG_I8K.
Option SENSORS_DELL_SMM is now used to enable compilation of dell-smm-hwmon
driver and old CONFIG_I8K option to enable /proc/i8k interface in driver.So this change allows to compile dell-smm-hwmon driver without legacy /proc/i8k
interface which is needed only for old Dell Inspirion models or for userspace
i8kutils package.For backward compatibility when CONFIG_I8K is enabled then also SENSORS_DELL_SMM
is enabled and so driver dell-smm-hwmon (with /proc/i8k) is compiled.Signed-off-by: Pali Rohár

Pull main powerpc updates from Ben Herrenschmidt:
"This time around, the powerpc merges are going to be a little bit more
complicated than usual.This is the main pull request with most of the work for this merge
window. I will describe it a bit more further down.There is some additional cpuidle driver work, however I haven't
included it in this tree as it depends on some work in tip/timer-core
which Thomas accidentally forgot to put in a topic branch. Since I
didn't want to carry all of that tip timer stuff in powerpc -next, I
setup a separate branch on top of Thomas tree with just that cpuidle
driver in it, and Stephen has been carrying that in next separately
for a while now. I'll send a separate pull request for it.Additionally, two new pieces in this tree add users for a sysfs API
that Tejun and Greg have been deprecating in drivers-core-next.
Thankfully Greg reverted the patch that removes the old API so this
merge can happen cleanly, but once merged, I will send a patch
adjusting our new code to the new API so that Greg can send you the
removal patch.Now as for the content of this branch, we have a lot of perf work for
power8 new counters including support for our new "nest" counters
(also called 24x7) under pHyp (not natively yet).We have new functionality when running under the OPAL firmware
(non-virtualized or KVM host), such as access to the firmware error
logs and service processor dumps, system parameters and sensors, along
with a hwmon driver for the latter.There's also a bunch of bug fixes accross the board, some LE fixes,
and a nice set of selftests for validating our various types of copy
loops.On the Freescale side, we see mostly new chip/board revisions, some
clock updates, better support for machine checks and debug exceptions,
etc..."* 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: (70 commits)

Pull battery updates from Anton Vorontsov:
"Highlights:- OpenFirmware/DeviceTree support for the Power Supply core: the core
now automatically populates supplied_from hierarchy from the device
tree. With these patches chargers and batteries can now lookup
each other without the board files support shim. Rhyland Klein at
NVIDIA did the work- New ST-Ericsson ABX500 hwmon driver. The driver is heavily using
the AB85xx core and depends on some recent changes to it, so that
is why the driver comes through the battery tree. It has an
appropriate ack from the hwmon maintainer (i.e. Guenter Roeck).
Martin Persson at ST-Ericsson and Hongbo Zhang at Linaro authored
the driver- Final bits to sync AB85xx ST-Ericsson changes into mainline. The
changes touch mfd parts, but these were acked by the appropriate
MFD maintainer (ie Samuel Ortiz). Lee Jones at Linaro did most of
the work and lead the submission process.Minor changes, but still worth mentioning:
