[PATCH v5 0/5] Let the power allocator thermal governor run on any thermal zone

Relax the thermal governor requirements of sustainable_power and at
least two trip points so that it can be bound to any thermal zone.
Its behavior won't be optimal, it would be the best possible with the
data provided.

Changes since v4:
- Fix crash when a thermal zone with no trip points has no
get_trip_point_temp(). Reported by Daniel Kurtz.
- s/estimate_controller_constants()/estimate_pid_constants()/g

Changes since v3:
- Don't hardcode a value for sustainable power and re-estimate
the PID controllers every time if no sustainable power is given
as suggested by Eduardo Valentin.
- power_actor_get_min_power() moved to a patch of its own.

Changes since v2:
- Typos suggested by Daniel Kurtz

Changes since v1:
- Let the power allocator governor operate if the thermal zone
doesn't have tzp as suggested by Chung-yih Wang

Javi Merino (5):
thermal: Add a function to get the minimum power
thermal: power_allocator: relax the requirement of a sustainable_power
in tzp
thermal: power_allocator: relax the requirement of two passive trip
points
thermal: power_allocator: don't require tzp to be present for the
thermal zone
thermal: power_allocator: exit early if there are no cooling devices
