Linus Torvalds 8cbd0eefca Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux
Pull thermal management updates from Zhang Rui:
 "There are not too many changes this time, except two new platform
  thermal drivers, ti-soc-thermal driver and x86_pkg_temp_thermal
  driver, and a couple of small fixes.

  Highlights:

   - move the ti-soc-thermal driver out of the staging tree to the
     thermal tree.

   - introduce the x86_pkg_temp_thermal driver.  This driver registers
     CPU digital temperature package level sensor as a thermal zone.

   - small fixes/cleanups including removing redundant use of
     platform_set_drvdata() and of_match_ptr for all platform thermal
     drivers"

Eduardo Valentin 57d1617137 thermal: ti-soc-thermal: use standard GPIO DT bindings
This change updates the ti-soc-thermal driver to use
standard GPIO DT bindings to read the GPIO number associated
to thermal shutdown IRQ, in case the device features it.

Previously, the code was using a specific DT bindings.
As now OMAP supports the standard way to model GPIOs,
there is no point in having a ti specific binding.

Randy Dunlap b3ba020652 thermal: fix x86_pkg_temp_thermal.c build and Kconfig
Fix build error in x86_pkg_temp_thermal.c.  It requires that
X86_MCE & X86_THERMAL_VECTOR be enabled, so depend on the latter symbol,
since it depends on X86_MCE (indirectly).

Also, X86_PKG_TEMP_THERMAL is already inside an "if THERMAL" block,
so remove that duplicated dependency.

Srinivas Pandruvada f1a18a1056 Thermal: CPU Package temperature thermal
This driver register CPU digital temperature sensor as a thermal
zone at package level.
Each package will show up as one zone with at max two trip points.
These trip points can be both read and updated. Once a non zero
value is set in the trip point, if the package package temperature
goes above or below this setting, a thermal notification is
generated.

Eduardo Valentin 0c872507d8 thermal: consider emul_temperature while computing trend
In case emulated temperature is in use, using the trend
provided by driver layer can lead to bogus situation.
In this case, debugger user would set a temperature value,
but the trend would be from driver computation.

To avoid this situation, this patch changes the get_tz_trend()
to consider the emulated temperature whenever that is in use.

Eduardo Valentin 8926fa4f9b thermal: ti-soc-thermal: add thermal data for DRA752 chips
This patch adds the thermal data for TI DRA752 chips.
In this change it includes (autogen):
. Register offset definitions
. Bitfields and masks for all registers
. Conversion table

Also, the thermal limits, thresholds and extrapolation
rules are included. The extrapolation rule is simply
add +2C as margin.

All 5 sensors, MPU, GPU, CORE, DSPEVE and IVA, are defined
and exposed. Only MPU has cooling device.

Eduardo Valentin 0c12b5ac82 thermal: ti-soc-thermal: remove usage of IS_ERR_OR_NULL
This patch changes the driver to avoid the usage of IS_ERR_OR_NULL()
macro. This macro can lead to dangerous results, like returning
success (0) during a failure scenario (NULL pointer handling).

For this reason this patch is changing the driver after
revisiting the code. These are the cases:
i. For cases in which IS_ERR_OR_NULL() is used for checking
return values of functions that returns either PTR_ERR()
or a valid pointer, it has been translated to IS_ERR() check only.
ii. For cases that a NULL check is still needed, it has been
translated to if (!ptr || IS_ERR(ptr)).

Shawn Guo 24c7a38172 thermal: cpu_cooling: fix 'descend' check in get_property()
The variable 'descend' is initialized as -1 in function get_property(),
and will never get any chance to be updated by the following code.

	if (freq != CPUFREQ_ENTRY_INVALID && descend != -1)
		descend = !!(freq > table[i].frequency);

This makes function get_property() return the wrong frequency for given
cooling level if the frequency table is sorted in ascending.  Fix it
by correcting the 'descend' check in if-condition to 'descend == -1'.
