Linus Torvalds 2efda9042d Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux
Pull thermal management update from Zhang Rui:
 "Summary:

   - of-thermal extension to allow drivers to register and use its
     functionality in a better way, without exploiting thermal core.
     From Lukasz Majewski.

   - Fix a bug in intel_soc_dts_thermal driver which calls a sleep
     function in interrupt handler.  From Maurice Petallo.

   - add a thermal UAPI header file for exporting the thermal generic
     netlink information to user-space.  From Florian Fainelli.

   - First round of refactoring in Exynos driver.  Bartlomiej and Lukasz
     are attempting to make it lean and easier to understand.

   - New thermal driver for Rockchip (rk3288), with support for DT
     thermal.  From Caesar Wang.

   - New thermal driver for Nvidia, Tegra124 SOCTHERM driver, with
     support for DT thermal.  From Mikko Perttunen.

   - New cooling device, based on common clock framework.  From Eduardo
     Valentin.

   - a couple of small fixes in thermal core framework.  From Srinivas
     Pandruvada, Javi Merino, Luis Henriques.

   - Dropping Armada A375-Z1 SoC thermal support as the chip is not in
     the market, armada folks decided to drop its support.

   - a couple of small fixes and cleanups in int340x thermal driver"

Linus Torvalds e6b5be2be4 Driver core patches for 3.19-rc1
Here's the set of driver core patches for 3.19-rc1.
 
 They are dominated by the removal of the .owner field in platform
 drivers.  They touch a lot of files, but they are "simple" changes, just
 removing a line in a structure.
 
 Other than that, a few minor driver core and debugfs changes.  There are
 some ath9k patches coming in through this tree that have been acked by
 the wireless maintainers as they relied on the debugfs changes.
 
 Everything has been in linux-next for a while.

Eduardo Valentin 2251aef64a thermal: of: improve of-thermal sensor registration API
Different drivers request API extensions in of-thermal. For this reason,
additional callbacks are required to fit the new drivers needs.

The current API implementation expects the registering sensor driver
to provide a get_temp and get_trend callbacks as function parameters.
As the amount of callbacks is growing, this patch changes the existing
implementation to use a .ops field to hold all the of thermal callbacks
to sensor drivers.

This patch also changes the existing of-thermal users to fit the new
API design. No functional change is introduced in this patch.

Arnaud Ebalard 6b19b66013 hwmon: (g762) fix call to devm_hwmon_device_register_with_groups()
g762_remove() needs to first call hwmon_device_unregister() and then
g762_of_clock_disable(). For that reason, it is not possible to
convert it to devm_hwmon_device_register_with_groups() and the
the non device managed version must be used.

This is correctly stated in commit message for 398e16db62 ("hwmon:
(g762) Convert to hwmon_device_register_with_groups") but the
associated changes do in fact introduce a call to the device managed
version of the function.

Because we build kernels with drivers built in for many platforms, it's
normal for the ibmpowernv driver to be loaded on systems that don't have
the appropriate hardware.

Currently the driver spams the log with:

  ibmpowernv ibmpowernv.0: Opal node 'sensors' not found
  ibmpowernv: Platfrom driver probe failed

But there is no error, this machine is not a powernv and doesn't have
the hardware. So change the sensors message to dev_dbg(), and only print
an error about the probe failing if it's not ENODEV.

Also fix the spelling of "Platfrom" and print the actual error value.

To get more comprehensive and integrated thermal management, it adds ntc

temperature to userspace via sysfs as it used to be.

Aravind Gopalakrishnan f89ce2706d hwmon: (k10temp) Add support for F15h M60h
This patch adds temperature monitoring support for F15h M60h processor.
 - Add new pci device id for the relevant processor
 - The functionality of REG_REPORTED_TEMPERATURE is moved to
   D0F0xBC_xD820_0CA4 [Reported Temperature Control]
   - So, use this to get CUR_TEMP value
   - Since we need an indirect register access, protect this with
     a mutex lock
 - Add Kconfig, Doc entries to indicate support for this processor.

Axel Lin 6ddd855c13 hwmon: (tmp103) Remove duplicate test for I2C_FUNC_SMBUS_BYTE_DATA functionality
Since commit b42261078a ("regmap: i2c: fallback to SMBus if the adapter
does not support standard I2C"), regmap-i2c will check the
I2C_FUNC_SMBUS_[BYTE|WORD]_DATA functionality based on the regmap_config
setting if the adapter does not support standard I2C.

So remove the I2C_FUNC_SMBUS_BYTE_DATA functionality check in the driver code.
