regulator: Updates for v4.3

Browse Source 
The biggest changes in the core this time around have been some
 refactorings that move us towards being able to drop the list of
 regulators maintained by the core and instead just use the driver model
 list maintained for the class devices for regulators which will make the
 code smaller and avoid some potential bugs.  Otherwise another fairly
 quiet release for the regulator API, highlights include:
 
  - A new API for setting voltages based on a minimum, target, maximum
    triplet.
  - Support for continuous voltage ranges rather than tables of explicit
    steps in the PWM regulator, requiring less explicit configuration.
  - New driver support for Dialog DA9215, Maxim 77843, Mediatek MT6311
    and Qualcomm RPM.

pwm regulator bindings
Bindings for the Generic PWM Regulator
======================================
Currently supports 2 modes of operation:
Voltage Table: When in this mode, a voltage table (See below) of
predefined voltage <=> duty-cycle values must be
provided via DT. Limitations are that the regulator can
only operate at the voltages supplied in the table.
Intermediary duty-cycle values which would normally
allow finer grained voltage selection are ignored and
rendered useless. Although more control is given to
the user if the assumptions made in continuous-voltage
mode do not reign true.
Continuous Voltage: This mode uses the regulator's maximum and minimum
supplied voltages specified in the
regulator-{min,max}-microvolt properties to calculate
appropriate duty-cycle values. This allows for a much
more fine grained solution when compared with
voltage-table mode above. This solution does make an
assumption that a %50 duty-cycle value will cause the
regulator voltage to run at half way between the
supplied max_uV and min_uV values.
Required properties:
- compatible: Should be "pwm-regulator"
- pwms: OF device-tree PWM specification (see PWM binding pwm.txt)
- voltage-table: voltage and duty table, include 2 members in each set of
brackets, first one is voltage(unit: uv), the next is duty(unit: percent)
--------------------
- compatible: Should be "pwm-regulator"
Any property defined as part of the core regulator binding defined in
regulator.txt can also be used.
- pwms: PWM specification (See: ../pwm/pwm.txt)
Example:
Only required for Voltage Table Mode:
- voltage-table: Voltage and Duty-Cycle table consisting of 2 cells
First cell is voltage in microvolts (uV)
Second cell is duty-cycle in percent (%)
NB: To be clear, if voltage-table is provided, then the device will be used
in Voltage Table Mode. If no voltage-table is provided, then the device will
be used in Continuous Voltage Mode.
Any property defined as part of the core regulator binding can also be used.
(See: ../regulator/regulator.txt)
Continuous Voltage Example:
pwm_regulator {
compatible = "pwm-regulator;
pwms = <&pwm1 0 8448 0>;
regulator-min-microvolt = <1016000>;
regulator-max-microvolt = <1114000>;
regulator-name = "vdd_logic";
};
Voltage Table Example:
pwm_regulator {
compatible = "pwm-regulator;
pwms = <&pwm1 0 8448 0>;
regulator-min-microvolt = <1016000>;
regulator-max-microvolt = <1114000>;
regulator-name = "vdd_logic";
/* Voltage Duty-Cycle */
voltage-table = <1114000 0>,
<1095000 10>,
<1076000 20>,
<1056000 30>,
<1036000 40>,
<1016000 50>;
regulator-min-microvolt = <1016000>;
