2 Power allocator governor tunables
22 The power allocator governor implements a
24 temperature as the control input and power as the controlled output:
48      | S |-----+----->| sum e |----->| X |--->| S |-->| S |-->|power     |
60 Sustainable power
63 An estimate of the sustainable dissipatable power (in mW) should be
65 sustained power that can be dissipated at the desired control
66 temperature.  This is the maximum sustained power for allocation at
67 the desired maximum temperature.  The actual sustained power can vary
72 the thermal ramp. For reference, the sustainable power of a 4" phone
74 depending on screen size). It is possible to have the power value
75 expressed in an abstract scale. The sustained power should be aligned
85 			sustainable-power = <2500>;
103 The implementation of the PID controller in the power allocator
115 value of `k_pu` will result in the governor granting very high power
158 Therefore, the proportional term alone linearly decreases power from
168 the exact power that the governor requests.  When the temperature

199 `get_requested_power()` calculates the power requested by the device
200 in milliwatts and stores it in @power .  It should return 0 on
