Subject: [PATCH 0/5] Add ACPI trip points parser helpers

Regarding thermal, the ACPI code parsing the trip points is duplicated
inside different Intel drivers. The generic ACPI thermal driver also
duplicates this code.

Those ACPI parsing actions are used to define trip points and these
ones are defined by, and specific to, the backend driver.

The different get_trip_* ops, also very similar between each other,
are using the specific trip point structure to return the requested
trip point information.

>From there, there is nothing new, all this can be converted to the
generic trip point.

The first patch provides the functions to parse trip point description
from the ACPI table but based on the generic trip point structure. The
other patches convert the different Intel driver to use the ACPI
functions along with a migration to the generic trip point.

Daniel Lezcano (5):
  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
  thermal/drivers/intel: Use generic trip points for quark_dts
  thermal/drivers/intel: Use generic trip points for
    processor_thermal_device_pci
