regulator: Updates for v6.6

Browse Source 
Other tha new device support and some minor fixes this has been a really
 quiet release, the only notable things are the new drivers.  There's a
 couple of MFDs among the new devices so the generic parts are pulled in:
 
  - Support for Analog Devices MAX77831/57/59, Awinc AW37503, Qualcom
    PMX75 and RFGEN, RealTek RT5733, RichTek RTQ2208 and Texas
    Instruments TPS65086.

maintainers:

description: |
RTQ2208 is a highly integrated power converter that offers functional safety dual
multi-configurable synchronous buck converters and two LDOs.
Bucks support "regulator-allowed-modes" and "regulator-mode". The former defines the permitted
switching operation in normal mode; the latter defines the operation in suspend to RAM mode.
No matter the RTQ2208 is configured to normal or suspend to RAM mode, there are two switching
operation modes for all buck rails, automatic power saving mode (Auto mode) and forced continuous
conduction mode (FCCM).
The definition of modes is in the datasheet which is available in below link
and their meaning is::
0 - Auto mode for power saving, which reducing the switching frequency at light load condition
to maintain high frequency.
1 - FCCM to meet the strict voltage regulation accuracy, which keeping constant switching frequency.
Datasheet will be available soon at
https://www.richtek.com/assets/Products

* Dialog Semiconductor SLG51000 Voltage Regulator
Required properties:
- compatible : Should be "dlg,slg51000" for SLG51000
- reg : Specifies the I2C slave address.
- xxx-supply: Input voltage supply regulator for ldo3 to ldo7.
These entries are required if regulators are enabled for a device.
An absence of these properties can cause the regulator registration to fail.
If some of input supply is powered through battery or always-on supply then
also it is required to have these parameters with proper node handle of always
on power supply.
vin3-supply: Input supply for ldo3
vin4-supply: Input supply for ldo4
vin5-supply: Input supply for ldo5
vin6-supply: Input supply for ldo6
vin7-supply: Input supply for ldo7
Optional properties:
- interrupt-parent : Specifies the reference to the interrupt controller.
- interrupts : IRQ line information.
- dlg,cs-gpios : Specify a valid GPIO for chip select
Sub-nodes:
- regulators : This node defines the settings for the regulators.
The content of the sub-node is defined by the standard binding
for regulators; see regulator.txt.
The SLG51000 regulators are bound using their names listed below:
ldo1
ldo2
ldo3
ldo4
ldo5
ldo6
ldo7
Optional properties for regulators:
- enable-gpios : Specify a valid GPIO for platform control of the regulator.
Example:
pmic: slg51000@75 {
compatible = "dlg,slg51000";
reg = <0x75>;
regulators {
ldo1 {
regulator-name = "ldo1";
regulator-min-microvolt = <2400000>;
regulator-max-microvolt = <3300000>;
};
ldo2 {

regulator-min-microvolt = <2400000>;
regulator-max-microvolt = <3300000>;
};
