 - Remove the clock cooling code as it is used nowhere (Amit Kucheria)

 - Add the rcar_gen3_thermal's r8a774e1 support (Marian-Cristian
   Rotariu)

 - Replace all references to thermal.txt in the documentation to the
   corresponding yaml files (Amit Kucheria)

 - Add maintainer entry for the IPA (Lukasz Luba)

 - Add support for MSM8939 for the tsens (Shawn Guo)

 - Update power allocator and devfreq cooling to SPDX licensing (Lukasz
   Luba)

 - Add Cannon Lake Low Power PCH support (Sumeet Pawnikar)

 - Add tsensor support for V2 mediatek thermal system (Henry Yen)

 - Fix thermal zone lookup by ID for the core code (Thierry Reding)
