When that is done, no get_trip_* ops are needed and they can be removed. Convert the ops content logic into generic trip points and register them with the thermal zone. In order to consolidate the code, use the ACPI thermal framework API to fill the generic trip point from the ACPI tables. It has been tested on a Intel i7-8650U - x280 with the INT3400, the PCH, ACPITZ, and x86_pkg_temp. No regression observed so far.
