regulator: Updates for v5.16 

Thanks to the removal of the unused TPS80021 driver the regulator
 updates for this cycle actually have a negative diffstat.  Otherwise
 it's been quite a quiet release, lots of fixes and small improvements
 with the biggest individual changes being several conversions of DT
 bindings to YAML format.

Binding for Samsung S2M and S5M family clock generator block
============================================================
This is a part of device tree bindings for S2M and S5M family multi-function
devices.
More information can be found in bindings/mfd/sec-core.txt file.
The S2MPS11/13/15 and S5M8767 provide three(AP/CP/BT) buffered 32.768 kHz
outputs. The S2MPS14 provides two (AP/BT) buffered 32.768 KHz outputs.
To register these as clocks with common clock framework instantiate under
main device node a sub-node named "clocks".
It uses the common clock binding documented in:
- Documentation/devicetree/bindings/clock/clock-bindings.txt
Required properties of the "clocks" sub-node:
- #clock-cells: should be 1.
- compatible: Should be one of: "samsung,s2mps11-clk", "samsung,s2mps13-clk",
"samsung,s2mps14-clk", "samsung,s5m8767-clk"
The S2MPS15 uses the same compatible as S2MPS13, as both provides similar
clocks.
Each clock is assigned an identifier and client nodes use this identifier
to specify the clock which they consume.
Clock ID Devices
----------------------------------------------------------
32KhzAP 0 S2MPS11/13/14/15, S5M8767
32KhzCP 1 S2MPS11/13/15, S5M8767
32KhzBT 2 S2MPS11/13/14/15, S5M8767
Include dt-bindings/clock/samsung,s2mps11.h file to use preprocessor defines
in device tree sources.
Example:
s2mps11_pmic@66 {
compatible = "samsung,s2mps11-pmic";
reg = <0x66>;
s2m_osc: clocks {
compatible = "samsung,s2mps11-clk";
#clock-cells = <1>;
clock-output-names = "xx", "yy", "zz";
};
};

* Maxim MAX8997 Voltage and Current Regulator
The Maxim MAX8997 is a multi-function device which includes voltage and
current regulators, rtc, charger controller and other sub-blocks. It is
interfaced to the host controller using a i2c interface. Each sub-block is
addressed by the host system using different i2c slave address. This document
describes the bindings for 'pmic' sub-block of max8997.
Required properties:
- compatible: Should be "maxim,max8997-pmic".
- reg: Specifies the i2c slave address of the pmic block. It should be 0x66.
- max8997,pmic-buck1-dvs-voltage: A set of 8 voltage values in micro-volt (uV)
units for buck1 when changing voltage using gpio dvs. Refer to [1] below
for additional information.
- max8997,pmic-buck2-dvs-voltage: A set of 8 voltage values in micro-volt (uV)
units for buck2 when changing voltage using gpio dvs. Refer to [1] below
for additional information.
- max8997,pmic-buck5-dvs-voltage: A set of 8 voltage values in micro-volt (uV)
units for buck5 when changing voltage using gpio dvs. Refer to [1] below
for additional information.
[1] If none of the 'max8997,pmic-buck[1/2/5]-uses-gpio-dvs' optional
property is specified, the 'max8997,pmic-buck[1/2/5]-dvs-voltage'
property should specify atleast one voltage level (which would be a
safe operating voltage).
If either of the 'max8997,pmic-buck[1/2/5]-uses-gpio-dvs' optional
property is specified, then all the eight voltage values for the
'max8997,pmic-buck[1/2/5]-dvs-voltage' should be specified.
Optional properties:
- interrupts: Interrupt specifiers for two interrupt sources.
- First interrupt specifier is for 'irq1' interrupt.
- Second interrupt specifier is for 'alert' interrupt.
- charger-supply: regulator node for charging current.
- max8997,pmic-buck1-uses-gpio-dvs: 'buck1' can be controlled by gpio dvs.
- max8997,pmic-buck2-uses-gpio-dvs: 'buck2' can be controlled by gpio dvs.
- max8997,pmic-buck5-uses-gpio-dvs: 'buck5' can be controlled by gpio dvs.
Additional properties required if either of the optional properties are used:
- max8997,pmic-ignore-gpiodvs-side-effect: When GPIO-DVS mode is used for
multiple bucks, changing the voltage value of one of the bucks may affect
that of another buck, which is the side effect of the change (set_voltage).
Use this property to ignore such side effects and change the voltage.
- max8997,pmic-buck125-default-dvs-idx: Default voltage setting selected from
the possible 8 options selectable by the dvs gpios. The value of this
property should be between 0 and 7. If not specified or if out of range, the
default value of this property is set to 0.
- max8997,pmic-buck125-dvs-gpios: GPIO specifiers for three host gpio's used
for dvs. The format of the gpio specifier depends in the gpio controller.
Regulators: The regulators of max8997 that have to be instantiated should be
included in a sub-node named 'regulators'. Regulator nodes included in this
sub-node should be of the format as listed below.
regulator_name {
standard regulator bindings here
};
The following are the names of the regulators that the max8997 pmic block
supports. Note: The 'n' in LDOn and BUCKn represents the LDO or BUCK number
as per the datasheet of max8997.
- LDOn
- valid values for n are 1 to 18 and 21
- Example: LDO0, LD01, LDO2, LDO21
- BUCKn
- valid values for n are 1 to 7.
- Example: BUCK1, BUCK2, BUCK3, BUCK7
- ENVICHG: Battery Charging Current Monitor Output. This is a fixed
voltage type regulator
- ESAFEOUT1: (ldo19)
- ESAFEOUT2: (ld020)
- CHARGER_CV: main battery charger voltage control
- CHARGER: main battery charger current control
- CHARGER_TOPOFF: end of charge current threshold level
The bindings inside the regulator nodes use the standard regulator bindings
which are documented elsewhere.

Binding for Samsung S2MPA01 regulator block
===========================================
This is a part of device tree bindings for S2M family multi-function devices.
More information can be found in bindings/mfd/sec-core.txt file.
The S2MPA01 device provide buck and LDO regulators.
To register these with regulator framework instantiate under main device node
a sub-node named "regulators" with more sub-nodes for each regulator using the
common regulator binding documented in:
- Documentation/devicetree/bindings/regulator/regulator.txt
Names of regulators supported by S2MPA01 device:
- LDOn
- valid values for n are 1 to 26
- Example: LDO1, LD02, LDO26
- BUCKn
- valid values for n are 1 to 10.
- Example: BUCK1, BUCK2, BUCK9
Note: The 'n' in LDOn and BUCKn represents the LDO or BUCK number
as per the datasheet of device.
Optional properties of buck regulator nodes under "regulators" sub-node:
- regulator-ramp-delay: ramp delay in uV/us. May be 6250, 12500
(default), 25000, or 50000. May be 0 for disabling the ramp delay on
BUCK{1,2,3,4}.
In the absence of the regulator-ramp-delay property, the default ramp
delay will be used.
Note: Some bucks share the ramp rate setting i.e. same ramp value
will be set for a particular group of bucks so provide the same
regulator-ramp-delay value for them.
Groups sharing ramp rate:
- buck{1,6},
- buck{2,4},
- buck{8,9,10}.
Example:
s2mpa01_pmic@66 {
compatible = "samsung,s2mpa01-pmic";
reg = <0x66>;
regulators {
ldo1_reg: LDO1 {
regulator-name = "VDD_ALIVE";

Binding for Samsung S2M family regulator block
==============================================
This is a part of device tree bindings for S2M family multi-function devices.
More information can be found in bindings/mfd/sec-core.txt file.
The S2MPS11/13/14/15 and S2MPU02 devices provide buck and LDO regulators.
To register these with regulator framework instantiate under main device node
a sub-node named "regulators" with more sub-nodes for each regulator using the

- Documentation/devicetree/bindings/regulator/regulator.txt
Names of regulators supported by different devices:
- LDOn
- valid values for n are:

- S2MPS13: 1 to 40
- S2MPS14: 1 to 25

- regulator-ramp-delay: ramp delay in uV/us. May be 6250, 12500,
25000 (default) or 50000.
Additionally S2MPS11 supports disabling ramp delay for BUCK{2,3,4,6}
by setting it to <0>.
Note: On S2MPS11 some bucks share the ramp rate setting i.e. same ramp value
will be set for a particular group of bucks so provide the same
regulator-ramp-delay value for them.
Groups sharing ramp rate:
- buck{1,6},
- buck{3,4},
- buck{7,8,10}.
- samsung,ext-control-gpios: On S2MPS14 the LDO10, LDO11 and LDO12 can be
configured to external control over GPIO. To turn this feature on this
property must be added to the regulator sub-node:
- samsung,ext-control-gpios: GPIO specifier for one GPIO
controlling this regulator (enable/disable)
Example:
LDO12 {
regulator-name = "V_EMMC_2.8V";
regulator-min-microvolt = <2800000>;
regulator-max-microvolt = <2800000>;
samsung,ext-control-gpios = <&gpk0 2 0>;

Binding for Samsung S5M8767 regulator block
===========================================
This is a part of device tree bindings for S5M family multi-function devices.
More information can be found in bindings/mfd/sec-core.txt file.
The S5M8767 device provide buck and LDO regulators.
To register these with regulator framework instantiate under main device node
a sub-node named "regulators" with more sub-nodes for each regulator using the
common regulator binding documented in:
- Documentation/devicetree/bindings/regulator/regulator.txt
Required properties of the main device node (the parent!):
- s5m8767,pmic-buck2-dvs-voltage: A set of 8 voltage values in micro-volt (uV)
units for buck2 when changing voltage using gpio dvs. Refer to [1] below
for additional information.
- s5m8767,pmic-buck3-dvs-voltage: A set of 8 voltage values in micro-volt (uV)
units for buck3 when changing voltage using gpio dvs. Refer to [1] below
for additional information.
- s5m8767,pmic-buck4-dvs-voltage: A set of 8 voltage values in micro-volt (uV)
units for buck4 when changing voltage using gpio dvs. Refer to [1] below
for additional information.
- s5m8767,pmic-buck-ds-gpios: GPIO specifiers for three host gpio's used
for selecting GPIO DVS lines. It is one-to-one mapped to dvs gpio lines.
[1] If none of the 's5m8767,pmic-buck[2/3/4]-uses-gpio-dvs' optional
property is specified, the 's5m8767,pmic-buck[2/3/4]-dvs-voltage'
property should specify atleast one voltage level (which would be a
safe operating voltage).
If either of the 's5m8767,pmic-buck[2/3/4]-uses-gpio-dvs' optional
property is specified, then all the eight voltage values for the
's5m8767,pmic-buck[2/3/4]-dvs-voltage' should be specified.
Optional properties of the main device node (the parent!):
- s5m8767,pmic-buck2-uses-gpio-dvs: 'buck2' can be controlled by gpio dvs.
- s5m8767,pmic-buck3-uses-gpio-dvs: 'buck3' can be controlled by gpio dvs.
- s5m8767,pmic-buck4-uses-gpio-dvs: 'buck4' can be controlled by gpio dvs.
Additional properties required if either of the optional properties are used:
- s5m8767,pmic-buck234-default-dvs-idx: Default voltage setting selected from
the possible 8 options selectable by the dvs gpios. The value of this
property should be between 0 and 7. If not specified or if out of range, the
default value of this property is set to 0.
- s5m8767,pmic-buck-dvs-gpios: GPIO specifiers for three host gpio's used
for dvs. The format of the gpio specifier depends in the gpio controller.
Names of regulators supported by S5M8767 device:
- LDOn
- valid values for n are 1 to 28
- Example: LDO1, LDO2, LDO28
- BUCKn
- valid values for n are 1 to 9.
- Example: BUCK1, BUCK2, BUCK9
Note: The 'n' in LDOn and BUCKn represents the LDO or BUCK number
as per the datasheet of device.
Optional properties of the nodes under "regulators" sub-node:
- op_mode: describes the different operating modes of the LDO's with
power mode change in SOC. The different possible values are,
0 - always off mode
1 - on in normal mode
2 - low power mode
3 - suspend mode
- s5m8767,pmic-ext-control-gpios: (optional) GPIO specifier for one
GPIO controlling this regulator
(enable/disable); This is valid only
for buck9.
