Srinivas Pandruvada 0e70f466fb thermal: Enhance thermal_zone_device_update for events
Added one additional parameter to thermal_zone_device_update() to provide
caller with an optional capability to specify reason.
Currently this event is used by user space governor to trigger different
processing based on event code. Also it saves an additional call to read
temperature when the event is received.
The following events are cuurently defined:
- Unspecified event
- New temperature sample
- Trip point violated
- Trip point changed
- thermal device up and down
- thermal device power capability changed

Andy Shevchenko 4077a387b7 x86/platform/iosf_mbi: Remove duplicate definitions
The read and write opcodes are global for all units on SoC and even across
Intel SoCs. Remove duplication of corresponding constants. At the same time
convert all current users.

No functional change.

Sascha Hauer 17e8351a77 thermal: consistently use int for temperatures
The thermal code uses int, long and unsigned long for temperatures
in different places.

Using an unsigned type limits the thermal framework to positive
temperatures without need. Also several drivers currently will report
temperatures near UINT_MAX for temperatures below 0°C. This will probably
immediately shut the machine down due to overtemperature if started below
0°C.

'long' is 64bit on several architectures. This is not needed since INT_MAX °mC
is above the melting point of all known materials.

Consistently use a plain 'int' for temperatures throughout the thermal code and
the drivers. This only changes the places in the drivers where the temperature
is passed around as pointer, when drivers internally use another type this is
not changed.

Wu Fengguang bd7081ae2b Thermal: Intel SoC: fix simple_return.cocci warnings
drivers/thermal/intel_soc_dts_iosf.c:358:4-7: WARNING: end returns can be simpified

 Simplify a trivial if-return sequence.  Possibly combine with a
 preceding function call.

Srinivas Pandruvada ee073604db Thermal: Intel SoC: DTS thermal IOSF core
This is becoming a common feature for Intel SoCs to expose the additional
digital temperature sensors (DTSs) using side band interface (IOSF). This
change remove common IOSF DTS handler function from the existing driver
intel_soc_dts_thermal.c and creates a stand alone module, which can
be selected from the SoC specific drivers. In this way there is less
code duplication.
