Pull thermal control updates from Rafael Wysocki:
 "The majority of changes here are related to the general switch-over to
  using arrays of generic trip point structures registered along with a
  thermal zone instead of trip point callbacks (this has been done
  mostly by Daniel Lezcano with some help from yours truly on the Intel
  drivers front).

  Apart from that and the related reorganization of code, there are some
  enhancements of the existing driver and a new Mediatek Low Voltage
  Thermal Sensor (LVTS) driver. The Intel powerclamp undergoes a major
  rework so it will use the generic idle_inject facility for CPU idle
  time injection going forward and it will take additional module
  parameters for specifying the subset of CPUs to be affected by it
  (work done by Srinivas Pandruvada).

  Also included are assorted fixes and a whole bunch of cleanups.

  Specifics:

   - Rework a large bunch of drivers to use the generic thermal trip
     structure and use the opportunity to do more cleanups by removing
     unused functions from the OF code (Daniel Lezcano)

   - Remove core header inclusion from drivers (Daniel Lezcano)

   - Fix some locking issues related to the generic thermal trip rework
     (Johan Hovold)

   - Fix a crash when requesting the critical temperature on tegra,
     which is related to the generic trip point work (Jon Hunter)

   - Clean up thermal device unregistration code (Viresh Kumar)

   - Fix and clean up thermal control core initialization error code
     paths (Daniel Lezcano)

   - Relocate the trip points handling code into a separate file (Daniel
     Lezcano)

   - Make the thermal core fail registration of thermal zones and
     cooling devices if the thermal class has not been registered
     (Rafael Wysocki)

   - Add trip point initialization helper functions for ACPI-defined
     trip points and modify two thermal drivers to use them (Rafael
     Wysocki, Daniel Lezcano)

   - Make the core thermal control code use sysfs_emit_at() instead of
     scnprintf() where applicable (ye xingchen)

   - Consolidate code accessing the Intel TCC (Thermal Control
     Circuitry) MSRs by introducing library functions for that and
     making the TCC-related code in thermal drivers use them (Zhang Rui)

   - Enhance the x86_pkg_temp_thermal driver to support dynamic tjmax
     changes (Zhang Rui)

   - Address an "unsigned expression compared with zero" warning in the
     intel_soc_dts_iosf thermal driver (Yang Li)

   - Update comments regarding two functions in the Intel Menlow thermal
     driver (Deming Wang)

   - Use sysfs_emit_at() instead of scnprintf() in the int340x thermal
     driver (ye xingchen)

   - Make the intel_pch thermal driver support the Wellsburg PCH (Tim
     Zimmermann)

   - Modify the intel_pch and processor_thermal_device_pci thermal
     drivers use generic trip point tables instead of thermal zone trip
     point callbacks (Daniel Lezcano)

   - Add production mode attribute sysfs attribute to the int340x
     thermal driver (Srinivas Pandruvada)

   - Rework dynamic trip point updates handling and locking in the
     int340x thermal driver (Rafael Wysocki)

   - Make the int340x thermal driver use a generic trip points table
     instead of thermal zone trip point callbacks (Rafael Wysocki,
     Daniel Lezcano)

   - Clean up and improve the int340x thermal driver (Rafael Wysocki)

   - Simplify and clean up the intel_pch thermal driver (Rafael Wysocki)

   - Fix the Intel powerclamp thermal driver and make it use the common
     idle injection framework (Srinivas Pandruvada)

   - Add two module parameters, cpumask and max_idle, to the Intel
     powerclamp thermal driver to allow it to affect only a specific
     subset of CPUs instead of all of them (Srinivas Pandruvada)

   - Make the Intel quark_dts thermal driver Use generic trip point
     objects instead of its own trip point representation (Daniel
     Lezcano)

   - Add toctree entry for thermal documents and fix two issues in the
     Intel powerclamp driver documentation (Bagas Sanjaya)

   - Use strscpy() to instead of strncpy() in the thermal core (Xu
     Panda)

   - Fix thermal_sampling_exit() (Vincent Guittot)

   - Add Mediatek Low Voltage Thermal Sensor (LVTS) driver (Balsam
     Chihi)

   - Add r8a779g0 RCar support to the rcar_gen3 thermal driver (Geert
     Uytterhoeven)

   - Fix useless call to set_trips() when resuming in the rcar_gen3
     thermal control driver and add interrupt support detection at init
     time to it (Niklas Söderlund)

   - Fix memory corruption in the hi3660 thermal driver (Yongqin Liu)

   - Fix include path for libnl3 in pkg-config file for libthermal
     (Vibhav Pant)

   - Remove syscfg-based driver for st as the platform is not supported
     any more (Alain Volmat)"

+Module Parameters
+=================
+
+``cpumask`` (RW)
+	A bit mask of CPUs to inject idle. The format of the bitmask is same as
+	used in other subsystems like in /proc/irq/\*/smp_affinity. The mask is
+	comma separated 32 bit groups. Each CPU is one bit. For example for a 256
+	CPU system the full mask is:
+	ffffffff,ffffffff,ffffffff,ffffffff,ffffffff,ffffffff,ffffffff,ffffffff
+
+	The rightmost mask is for CPU 0-32.
+
+``max_idle`` (RW)
+	Maximum injected idle time to the total CPU time ratio in percent range
+	from 1 to 100. Even if the cooling device max_state is always 100 (100%),
+	this parameter allows to add a max idle percent limit. The default is 50,
+	to match the current implementation of powerclamp driver. Also doesn't
+	allow value more than 75, if the cpumask includes every CPU present in
+	the system.
