2 Linux voltage and current regulator framework
9 voltage and current regulators.
13 regulators (where voltage output is controllable) and current sinks (where
14 current limit is controllable).
26   - Regulator
27                  - Electronic device that supplies power to other devices.
29                    some can control their output voltage and or current.
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:-
44                    current limit. It only needs to enable or disable its
49                    current limit to meet operation demands.
52   - Power Domain
53                  - Electronic circuit that is supplied its input power by the

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
108                      - Domain-1 voltage is 3300mV
109                      - Domain-2 voltage is 1400mV -> 1600mV
110                      - Domain-3 current limit is 0mA -> 20mA.

115                    e.g. a consumer backlight driver asks for a current increase
117                    to through the levels as follows :-

128                    Regulator Domains: is the new current limit within the
139 relevant to non SoC devices and is split into the following four interfaces:-
146       get/set voltage, current limit, mode, enable and disable. This should
147       allow consumers complete control over their supply voltage and current
148       limit. This also compiles out if not in use so drivers can be reused in
164       voltage/current domains (with constraints) for each regulator. It can
