[v2,0/3] Thermal ACPI APIs for generic trip points

Message

Recently sent as a RFC, the thermal ACPI for generic trip points is a set of
functions to fill the generic trip points structure which will become the
standard structure for the thermal framework and its users.

Different Intel drivers and the ACPI thermal driver are using the ACPI tables to
get the thermal zone information. As those are getting the same information,
providing this set of ACPI function with the generic trip points will
consolidate the code.

Also, the Intel PCH and the Intel 34xx drivers are converted to use the generic
trip points relying on the ACPI generic trip point parsing functions.

These changes have been tested on a Thinkpad Lenovo x280 with the PCH and
INT34xx drivers. No regression have been observed, the trip points remain the
same for what is described on this system.

Changelog:

 - V2:
   - Fix the thermal ACPI patch where the thermal_acpi.c was not included in
     the series

   - Provide a couple of users of this API which could have been tested on a
     real system

Daniel Lezcano (3):
  thermal/acpi: Add ACPI trip point routines
  thermal/drivers/intel: Use generic trip points for intel_pch
  thermal/drivers/intel: Use generic trip points int340x
