regulator: Updates for v5.10

Browse source 
This is a fairly small release for the regulator API, there's quite a
 few new devices supported and some important improvements around coupled
 regulators in the core but mostly just small fixes and improvements
 otherwise.
 
  - Fixes and cleanups around the handling of coupled regulators.
  - A special driver for some Raspberry Pi panels with some unusually
    custom stuff around them.
  - Support for Qualcomm PM660/PM660L, PM8950 and PM8953, Richtek RT4801
    and RTMV20, Rohm BD9576MUF and BD9573MUF.

Monolithic Power Systems MP8867/MP8869 voltage regulator
Required properties:
- compatible: Must be one of the following.
"mps,mp8867"
"mps,mp8869"
- reg: I2C slave address.
- enable-gpios: enable gpios.
- mps,fb-voltage-divider: An array of two integers containing the resistor
values R1 and R2 of the feedback voltage divider in kilo ohms.
Any property defined as part of the core regulator binding, defined in
./regulator.txt, can also be used.
Example:
vcpu: regulator@62 {
compatible = "mps,mp8869";
regulator-name = "vcpu";
regulator-min-microvolt = <700000>;
regulator-max-microvolt = <850000>;
regulator-always-on;
regulator-boot-on;
enable-gpios = <&porta 1 GPIO_ACTIVE_LOW>;
mps,fb-voltage-divider = <80 240>;
reg = <0x62>;

PFUZE100 family of regulators
Required properties:
- compatible: "fsl,pfuze100", "fsl,pfuze200", "fsl,pfuze3000", "fsl,pfuze3001"
- reg: I2C slave address
Optional properties:
- fsl,pfuze-support-disable-sw: Boolean, if present disable all unused switch
regulators to save power consumption. Attention, ensure that all important
regulators (e.g. DDR ref, DDR supply) has set the "regulator-always-on"
property. If not present, the switched regulators are always on and can't be
disabled. This binding is a workaround to keep backward compatibility with
old dtb's which rely on the fact that the switched regulators are always on
and don't mark them explicit as "regulator-always-on".
- fsl,pmic-stby-poweroff: if present, configure the PMIC to shutdown all
power rails when PMIC_STBY_REQ line is asserted during the power off sequence.
Use this option if the SoC should be powered off by external power
management IC (PMIC) on PMIC_STBY_REQ signal.
As opposite to PMIC_STBY_REQ boards can implement PMIC_ON_REQ signal.
Required child node:
- regulators: This is the list of child nodes that specify the regulator
initialization data for defined regulators. Please refer to below doc
Documentation/devicetree/bindings/regulator/regulator.txt.
The valid names for regulators are:

IC (PMIC) on PMIC_STBY_REQ signal.
As opposite to PMIC_STBY_REQ boards can implement PMIC_ON_REQ signal.

description: |
Richtek RTMV20 is a load switch current regulator that can supply up to 6A.
It is used to drive laser diode. There're two signals for chip controls
(Enable/Fail), Enable pin to turn chip on, and Fail pin as fault indication.
There're still four pins for camera control, two inputs (strobe and vsync),
the others for outputs (fsin1 and fsin2). Strobe input to start the current
supply, vsync input from IR camera, and fsin1/fsin2 output for the optional.
