Subject: [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
