87976ce282 hwmon: Add Baikal-T1 PVT sensor driver
Baikal-T1 SoC provides an embedded process, voltage and temperature
sensor to monitor an internal SoC environment (chip temperature, supply
voltage and process monitor) and on time detect critical situations,
which may cause the system instability and even damages. The IP-block
is based on the Analog Bits PVT sensor, but is equipped with a
dedicated control wrapper, which provides a MMIO registers-based access
to the sensor core functionality (APB3-bus based) and exposes an
additional functions like thresholds/data ready interrupts, its status
and masks, measurements timeout. All of these is used to create a hwmon
driver being added to the kernel by this commit.

The driver implements support for the hardware monitoring capabilities
of Baikal-T1 process, voltage and temperature sensors. PVT IP-core
consists of one temperature and four voltage sensors, each of which is
implemented as a dedicated hwmon channel config.

The driver can optionally provide the hwmon alarms for each sensor the
PVT controller supports. The alarms functionality is made compile-time
configurable due to the hardware interface implementation peculiarity,
which is connected with an ability to convert data from only one sensor
at a time. Additional limitation is that the controller performs the
thresholds checking synchronously with the data conversion procedure.
Due to these limitations in order to have the hwmon alarms
automatically detected the driver code must switch from one sensor to
another, read converted data and manually check the threshold status
bits. Depending on the measurements timeout settings this design may
cause additional burden on the system performance. By default if the
alarms kernel config is disabled the data conversion is performed by
the driver on demand when read operation is requested via corresponding
_input-file.

6bdf8f3efe hwmon: (drivetemp) Use drivetemp's true module name in Kconfig section
The addition of the support for reading the temperature of ATA drives as
per commit 5b46903d8b ("hwmon: Driver for disk and solid state drives
with temperature sensors") lists in the respective Kconfig section the
name of the module to be optionally built as "satatemp".

However, building the kernel modules with "CONFIG_SENSORS_DRIVETEMP=m",
does not generate a file named "satatemp.ko".

Instead, the rest of the original commit uses the term "drivetemp" and
a file named "drivetemp.ko" ends up in the kernel's modules directory.
This file has the right ingredients:

	$ strings /path/to/drivetemp.ko | grep ^description
	description=Hard drive temperature monitor

and modprobing it produces the expected result:

	# drivetemp is not loaded
	$ sensors -u drivetemp-scsi-4-0
	Specified sensor(s) not found!
	$ sudo modprobe drivetemp
	$ sensors -u drivetemp-scsi-4-0
	drivetemp-scsi-4-0
	Adapter: SCSI adapter
	temp1:
	  temp1_input: 35.000
	  temp1_max: 60.000
	  temp1_min: 0.000
	  temp1_crit: 70.000
	  temp1_lcrit: -40.000
	  temp1_lowest: 20.000
	  temp1_highest: 36.000

Fix Kconfig by referring to the true name of the module.

The purpose of this IP Core is to control the fan used for the cooling of a
Xilinx Zynq Ultrascale+ MPSoC without the need of any external temperature
sensors. To achieve this, the IP core uses the PL SYSMONE4 primitive to
obtain the PL temperature and, based on those readings, it then outputs
a PWM signal to control the fan rotation accordingly.

5b46903d8b hwmon: Driver for disk and solid state drives with temperature sensors
Reading the temperature of ATA drives has been supported for years
by userspace tools such as smarttools or hddtemp. The downside of
such tools is that they need to run with super-user privilege, that
the temperatures are not reported by standard tools such as 'sensors'
or 'libsensors', and that drive temperatures are not available for use
in the kernel's thermal subsystem.

This driver solves this problem by adding support for reading the
temperature of ATA drives from the kernel using the hwmon API and
by adding a temperature zone for each drive.

With this driver, the hard disk temperature can be read using the
unprivileged 'sensors' application:

$ sensors drivetemp-scsi-1-0
drivetemp-scsi-1-0
Adapter: SCSI adapter
temp1:        +23.0°C

or directly from sysfs:

$ grep . /sys/class/hwmon/hwmon9/{name,temp1_input}
/sys/class/hwmon/hwmon9/name:drivetemp
/sys/class/hwmon/hwmon9/temp1_input:23000

If the drive supports SCT transport and reports temperature limits,
those are reported as well.

drivetemp-scsi-0-0
Adapter: SCSI adapter
temp1:        +27.0°C  (low  =  +0.0°C, high = +60.0°C)
                       (crit low = -41.0°C, crit = +85.0°C)
                       (lowest = +23.0°C, highest = +34.0°C)

The driver attempts to use SCT Command Transport to read the drive
temperature. If the SCT Command Transport feature set is not available,
or if it does not report the drive temperature, drive temperatures may
be readable through SMART attributes. Since SMART attributes are not well
defined, this method is only used as fallback mechanism.

In the long run I even believe that we should drop the option and
enable the feature unconditionally. It doesn't do anything until the
user explicitly starts twiddling with sysfs attributes anyway.

4f8d374b77 hwmon: (max6650) add thermal cooling device capability
This allows max6650 devices to be referenced in dts as a cooling device.

The pwm value seems duplicated in cooling_dev_state but since pwm goes
through rounding logic into data->dac, it is modified and messes with
the thermal zone state algorithms. It's also better to serve a cache
value, thus avoiding periodic actual i2c traffic.

8636a1f967 treewide: surround Kconfig file paths with double quotes
The Kconfig lexer supports special characters such as '.' and '/' in
the parameter context. In my understanding, the reason is just to
support bare file paths in the source statement.

I do not see a good reason to complicate Kconfig for the room of
ambiguity.

The majority of code already surrounds file paths with double quotes,
and it makes sense since file paths are constant string literals.

Make it treewide consistent now.

5b5513b880 hwmon: Add On-Chip Controller (OCC) hwmon driver
The OCC is a device embedded on a POWER processor that collects and
aggregates sensor data from the processor and system. The OCC can
provide the raw sensor data as well as perform thermal and power
management on the system.

This driver provides a hwmon interface to the OCC from a service
processor (e.g. a BMC). The driver supports both POWER8 and POWER9 OCCs.
Communications with the POWER8 OCC are established over standard I2C
bus. The driver communicates with the POWER9 OCC through the FSI-based
OCC driver, which handles the lower-level communication details.

This patch lays out the structure of the OCC hwmon driver. There are two
platform drivers, one each for P8 and P9 OCCs. These are probed through
the I2C tree and the FSI-based OCC driver, respectively. The patch also
defines the first common structures and methods between the two OCC
versions.

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.

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.

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.

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..."

151173e8ce 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
   (i.e. Samuel Ortiz). Lee Jones at Linaro did most of the work and lead
   the submission process.
 
 Minor changes, but still worth mentioning:
 
 - Battery temperature reporting fix for Nokia N900 phones;
 - Versatile Express poweroff driver moved into drivers/power/reset/.
 - Tree-wise: use devm_kzalloc() where appropriate;
 - Tree-wise: dev_pm_ops cleanups/fixes.

51c2a4871c hwmon: (adt7410) Add support for the adt7310/adt7320
The adt7310/adt7320 is the SPI version of the adt7410/adt7420. The register map
layout is a bit different, i.e. the register addresses differ between the two
variants, but the bit layouts of the individual registers are identical. So both
chip variants can easily be supported by the same driver. The issue of non
matching register address layouts is solved by a simple look-up table which
translates the I2C addresses to the SPI addresses.

The patch moves the bulk of the adt7410 driver to a common module that will be
shared by the adt7410 and adt7310 drivers. This common module implements the
driver logic and uses a set of virtual functions to perform IO access. The
adt7410 and adt7310 driver modules provide proper implementations of these IO
accessor functions for I2C respective SPI.

This driver uses channel maps, defined either through device tree

of its channels.

 The only non move changes here concern the description and changes to the
 dependencies to IIO explicit and hwmon implicit.

 I'm proposing moving this into hwmon on the basis of placing drivers
 based on what they provide rather than what their underlying hardware
 is.

72cbdddcc1 hwmon: (coretemp) Drop dependency on PCI for TjMax detection on Atom CPUs
So far, we use the NM10 Express Chipset PCI chip ID to detect TjMax for
Atom CPUs with model 0x1c. As it turns out, we can use the CPU stepping
(x86_mask) for the same purpose; stepping is 10 for all model 0x1c CPUs
with TjMax of 100 degrees C. This was verified by checking the output of
/proc/cpuinfo for the respective CPUs (D4xx, D5xx, N4xx, N5xx).

Other CPUs currently covered by the same code (Exx, Z6xx, Z2460) are not
supported by the NM10 Express Chipset. Most of those CPUs have TjMax of 90
degrees C, except for E6xxT models which have a TjMax of 110 degrees C.
E6xxT CPUs can however not be detected by software.

Calculate TjMax for Atom CPUs as follows. Note that the listed values are not
correct in some cases (230, 330). tjmax_table is used for those to override
the default values.

ID	Stepping	TjMax		Models
0x1c	10		100		D4xx, N4xx, D5xx, N5xx
0x1c	not 10		90		Z5xx, N2xx, 230, 330, others
0x26	-		90		Atom Tunnel Creek (Exx),
					Lincroft (Z6xx)
0x27	-		90		Atom Medfield (Z2460)
0x36	-		100		Atom Cedar Trail (N2xxx, D2xxx)

Also drop the module dependency on PCI.

c48cbba6fe hwmon: exynos4: move thermal sensor driver to driver/thermal directory
This movement is needed because the hwmon entries and corresponding sysfs
interface is a duplicate of utilities already provided by
driver/thermal/thermal_sys.c.  The goal is to place it in thermal folder
and add necessary functions to use the in-kernel thermal interfaces.

Add support for the watchdog integrated into the SMSC SCH5627 and
SCH5636 superio-s. Since the watchdog is part of the hwmon logical device
and thus shares ioports with it, the watchdog driver is integrated into the
existing hwmon drivers for these.

Note that this version of the watchdog support for sch56xx superio-s
implements the watchdog chardev interface itself, rather then relying on
the recently added watchdog core / watchdog_dev. This is done because
currently some needed functionality is missing from watchdog_dev, as soon
as this functionality is added (which is being discussed on the
linux-watchdog mailinglist), I'll convert this driver over to using
watchdog_dev.
