d5553c2619 hwmon: (aspeed-pwm) add THERMAL dependency
With CONFIG_THERMAL=m, a built-in aspeed pwm tacho driver causes
a link error:

drivers/hwmon/aspeed-pwm-tacho.o: In function `aspeed_pwm_tacho_probe':
aspeed-pwm-tacho.c:(.text+0x7f0): undefined reference to `thermal_of_cooling_device_register'

This adds a dependency similar to what other hwmon drivers use,
ensuring that the aspeed driver cannot be built-in in this
case but has to be a module. With THERMAL=n, we still allow building it.

2d7a548a3e drivers: hwmon: Support for ASPEED PWM/Fan tach
The ASPEED AST2400/2500 PWM controller supports 8 PWM output ports.
The ASPEED AST2400/2500 Fan tach controller supports 16 tachometer
inputs.
The device driver matches on the device tree node. The configuration
values are read from the device tree and written to the respective
registers.
The driver provides a sysfs entries through which the user can
configure the duty-cycle value (ranging from 0 to 100 percent) and read
the fan tach rpm value.

28a340db90 hwmon: (tmp102) Convert to use regmap, and drop local cache
By converting the driver to regmap, we can use regmap to cache non-volatile
registers. Stop caching the temperature register; while potentially reading
it more often can result in reading it more often than necessary, this is
offset by the gain due to not re-reading the limit registers.

A positive side effect of this change is that limit registers can now be
read and updated before the first temperature conversion is complete.

This uses the same Kconfig trick that we have in a couple of other
drivers already to ensure we can only select the driver in valid
configurations when either THERMAL_OF is disabled, or when with a
dependency on CONFIG_THERMAL that can force SCPI to be a loadable
module in the case I was hitting.

b44a3d2a85 ARM: SoC driver updates for v4.4
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.
 - A driver to talk to the firmware on Raspberry Pi.

The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is

functionality only, can still be compiled if GPIOLIB is not enabled.

Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where
appropriate.

039ae58503 hwmon: Allow to compile dell-smm-hwmon driver without /proc/i8k
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.

59cf4243e5 hwmon: (ntc_thermistor) Fix dependencies
In commit 9e8269de, support was added for ntc_thermistor devices being
declared in the device tree and implemented on top of IIO. With that
change, a dependency was added to the ntc_thermistor driver:

	depends on (!OF && !IIO) || (OF && IIO)

This construct has the drawback that the driver can no longer be
selected when OF is set and IIO isn't, nor when IIO is set and OF is
not. This is a regression for the original users of the driver.

As the new code depends on IIO and is useless without OF, include it
only if both are enabled, and set the dependencies accordingly. This
is clearer, more simple and more correct.

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..."
