11 The intention is to allow systems to dynamically control regulator power output
12 in order to save power and prolong battery life. This applies to both voltage
26 - Regulator
27 - Electronic device that supplies power to other devices.
31 Input Voltage -> Regulator -> Output Voltage
34 - PMIC
35 - Power Management IC. An IC that contains numerous
39 - Consumer
40 - Electronic device that is supplied power by a regulator.
41 Consumers can be classified into two types:-
45 power supply. Its supply voltage is set by the hardware,
52 - Power Domain
53 - Electronic circuit that is supplied its input power by the
54 output power of a regulator, switch or by another power
59 Regulator -+-> Switch-1 -+-> Switch-2 --> [Consumer A]
61 | +-> [Consumer B], [Consumer C]
63 +-> [Consumer D], [Consumer E]
65 That is one regulator and three power domains:
67 - Domain 1: Switch-1, Consumers D & E.
68 - Domain 2: Switch-2, Consumers B & C.
69 - Domain 3: Consumer A.
71 and this represents a "supplies" relationship:
73 Domain-1 --> Domain-2 --> Domain-3.
75 A power domain may have regulators that are supplied power
78 Regulator-1 -+-> Regulator-2 -+-> [Consumer A]
80 +-> [Consumer B]
82 This gives us two regulators and two power domains:
84 - Domain 1: Regulator-2, Consumer B.
85 - Domain 2: Consumer A.
87 and a "supplies" relationship:
89 Domain-1 --> Domain-2
92 - Constraints
93 - Constraints are used to define power levels for performance
100 - voltage output is in the range 800mV -> 3500mV.
101 - regulator current output limit is 20mA @ 5V but is
104 Power Domain Level: This is defined in software by kernel
106 power domain to a particular power range. i.e.
108 - Domain-1 voltage is 3300mV
109 - Domain-2 voltage is 1400mV -> 1600mV
110 - Domain-3 current limit is 0mA -> 20mA.
117 to through the levels as follows :-
