-Regulator DT binding for MAX77620 Power management IC from Maxim Semiconductor.
-
-Device has multiple DCDC(sd[0-3] and LDOs(ldo[0-8]). The input supply
-of these regulators are defined under parent device node.
-Details of regulator properties are defined as child node under
-sub-node "regulators" which is child node of device node.
-
-Please refer file <Documentation/devicetree/bindings/regulator/regulator.txt>
-for common regulator bindings used by client.
-
-Following are properties of parent node related to regulators.
-
-Optional properties:
--------------------
-The input supply of regulators are the optional properties on the
-parent device node. The input supply of these regulators are provided
-through following properties:
-in-sd0-supply: Input supply for SD0, INA-SD0 or INB-SD0 pins.
-in-sd1-supply: Input supply for SD1.
-in-sd2-supply: Input supply for SD2.
-in-sd3-supply: Input supply for SD3.

-in-ldo4-6-supply: Input supply for LDO4 and LDO6.
-in-ldo7-8-supply: Input supply for LDO7 and LDO8.
-
-Optional sub nodes for regulators under "regulators" subnode:
-------------------------------------------------------------
-The subnodes name is the name of regulator and it must be one of:
- sd[0-3], ldo[0-8]
-
-Each sub-node should contain the constraints and initialization
-information for that regulator. The definition for each of these
-nodes is defined using the standard binding for regulators found at
-<Documentation/devicetree/bindings/regulator/regulator.txt>.
-
-There are also additional properties for SD/LDOs. These additional properties
-are required to configure FPS configuration parameters for SDs and LDOs.
-Please refer <devicetree/bindings/mfd/max77620.txt> for more detail of Flexible
-Power Sequence (FPS).
-Following are additional properties:
-
-- maxim,active-fps-source: FPS source for the regulators to get
- enabled/disabled when system is in
- active state. Valid values are:
- - MAX77620_FPS_SRC_0,
- FPS source is FPS0.
- - MAX77620_FPS_SRC_1,
- FPS source is FPS1
- - MAX77620_FPS_SRC_2 and
- FPS source is FPS2
- - MAX77620_FPS_SRC_NONE.
- Regulator is not controlled
- by FPS events and it gets
- enabled/disabled by register
- access.
- Absence of this property will leave
- the FPS configuration register for that
- regulator to default configuration.
-
-- maxim,active-fps-power-up-slot: Sequencing event slot number on which
- the regulator get enabled when
- master FPS input event set to HIGH.
- Valid values are 0 to 7.
- This is applicable if FPS source is
- selected as FPS0, FPS1 or FPS2.
-
-- maxim,active-fps-power-down-slot: Sequencing event slot number on which
- the regulator get disabled when master
- FPS input event set to LOW.
- Valid values are 0 to 7.
- This is applicable if FPS source is
- selected as FPS0, FPS1 or FPS2.
-
-- maxim,suspend-fps-source: This is same as property
- "maxim,active-fps-source" but value
- get configured when system enters in
- to suspend state.
-
-- maxim,suspend-fps-power-up-slot: This is same as property
- "maxim,active-fps-power-up-slot" but
- this value get configured into FPS
- configuration register when system
- enters into suspend.
- This is applicable if suspend state
- FPS source is selected as FPS0, FPS1 or
-
-- maxim,suspend-fps-power-down-slot: This is same as property
- "maxim,active-fps-power-down-slot" but
- this value get configured into FPS
- configuration register when system

- This is applicable if suspend state
- FPS source is selected as FPS0, FPS1 or
- FPS2.
-- maxim,ramp-rate-setting: integer, ramp rate(uV/us) setting to be
- configured to the device.
- The platform may have different ramp
- rate than advertised ramp rate if it has
- design variation from Maxim's
- recommended. On this case, platform
- specific ramp rate is used for ramp time
- calculation and this property is used
- for device register configurations.
- The measured ramp rate of platform is
- provided by the regulator-ramp-delay
- as described in <devicetree/bindings/
- regulator/regulator.txt>.
- Maxim Max77620 supports following ramp
- delay:
- SD: 13.75mV/us, 27.5mV/us, 55mV/us
- LDOs: 5mV/us, 100mV/us
-
-Note: If the measured ramp delay is same as advertised ramp delay then it is not
-required to provide the ramp delay with property "maxim,ramp-rate-setting". The
-ramp rate can be provided by the regulator-ramp-delay which will be used for
-ramp time calculation for voltage change as well as for device configuration.

Underscores are not allowed in general, so pattern needs fixes. Does
anything actually rely on this name? Is this ABI? I don't see old
binding and driver using the name, thus this should be just ^pin-[0-7]$
(+ is also not correct if you have max 8 gpios)

Old txt schema uses pin_gpio[0-7] hence it is here, but greping trees
did not reveal use of pin_gpio so it may be dropped.
No this is not ABI, name may be any. Including gpio0-1-2-3, gpio2-4
etc which is why + is there. or maybe you know better way to cover
those names?
There are device trees which use gpio5_6 with the underscore
(tegra210-smaug.dts; tegra210-p2894.dtsi for example). Should the
schema account for those?

Defining a specific pattern looks like an endorsement of the name. I
would just do the minimum you need. Something like '^(pin|gpio).' unless
you have a pinctrl-* property.

Binding for MAX77620 GPIO function is covered by the MAX77620 schema. GPIO
controller function in MAX77620 has no dedicated node and is folded into
the parent node itself.

Convert max77620 devicetree bindings from TXT to YAML format. This patch
does not change any functionality; the bindings remain the same. The
thermal bindings are incorporated into the binding.

-MAX77620 Power management IC from Maxim Semiconductor.
-
-Required properties:
--------------------
-- compatible: Must be one of
- "maxim,max77620"
- "maxim,max20024"
- "maxim,max77663"
-- reg: I2C device address.
-
-Optional properties:
--------------------
-- interrupts: The interrupt on the parent the controller is
- connected to.
-- interrupt-controller: Marks the device node as an interrupt controller.
-- #interrupt-cells: is <2> and their usage is compliant to the 2 cells
- variant of <../interrupt-controller/interrupts.txt>
- IRQ numbers for different interrupt source of MAX77620
- are defined at dt-bindings/mfd/max77620.h.
-
-- system-power-controller: Indicates that this PMIC is controlling the
- system power, see [1] for more details.
-
-[1] Documentation/devicetree/bindings/power/power-controller.txt
-
-Optional subnodes and their properties:
-=======================================
-
-Flexible power sequence configurations:
---------------------------------------
-The Flexible Power Sequencer (FPS) allows each regulator to power up under
-hardware or software control. Additionally, each regulator can power on
-independently or among a group of other regulators with an adjustable power-up
-and power-down delays (sequencing). GPIO1, GPIO2, and GPIO3 can be programmed
-to be part of a sequence allowing external regulators to be sequenced along
-with internal regulators. 32KHz clock can be programmed to be part of a
-sequence.
-
-The flexible sequencing structure consists of two hardware enable inputs
-(EN0, EN1), and 3 master sequencing timers called FPS0, FPS1 and FPS2.
-Each master sequencing timer is programmable through its configuration
-register to have a hardware enable source (EN1 or EN2) or a software enable
-source (SW). When enabled/disabled, the master sequencing timer generates
-eight sequencing events on different time periods called slots. The time
-period between each event is programmable within the configuration register.
-Each regulator, GPIO1, GPIO2, GPIO3, and 32KHz clock has a flexible power
-sequence slave register which allows its enable source to be specified as
-a flexible power sequencer timer or a software bit. When a FPS source of
-regulators, GPIOs and clocks specifies the enable source to be a flexible
-power sequencer, the power up and power down delays can be specified in
-the regulators, GPIOs and clocks flexible power sequencer configuration
-registers.
-
-When FPS event cleared (set to LOW), regulators, GPIOs and 32KHz
-clock are set into following state at the sequencing event that
-corresponds to its flexible sequencer configuration register.
- Sleep state: In this state, regulators, GPIOs
- and 32KHz clock get disabled at
- the sequencing event.
- Global Low Power Mode (GLPM): In this state, regulators are set in
- low power mode at the sequencing event.
-
-The configuration parameters of FPS is provided through sub-node "fps"
-and their child for FPS specific. The child node name for FPS are "fps0",
-"fps1", and "fps2" for FPS0, FPS1 and FPS2 respectively.
-
-The FPS configurations like FPS source, power up and power down slots for
-regulators, GPIOs and 32kHz clocks are provided in their respective
-configuration nodes which is explained in respective sub-system DT
-binding document.
-
-There is need for different FPS configuration parameters based on system
-state like when system state changed from active to suspend or active to
-power off (shutdown).
-
-Optional properties:
--------------------
--maxim,fps-event-source: u32, FPS event source like external
- hardware input to PMIC i.e. EN0, EN1 or
- software (SW).
- The macros are defined on
- dt-bindings/mfd/max77620.h
- for different control source.
- - MAX77620_FPS_EVENT_SRC_EN0
- for hardware input pin EN0.
- - MAX77620_FPS_EVENT_SRC_EN1
- for hardware input pin EN1.
- - MAX77620_FPS_EVENT_SRC_SW
- for software control.
-
--maxim,shutdown-fps-time-period-us: u32, FPS time period in microseconds
- when system enters in to shutdown
- state.
-
--maxim,suspend-fps-time-period-us: u32, FPS time period in microseconds
- when system enters in to suspend state.
-
--maxim,device-state-on-disabled-event: u32, describe the PMIC state when FPS
- event cleared (set to LOW) whether it
- should go to sleep state or low-power
- state. Following are valid values:
- - MAX77620_FPS_INACTIVE_STATE_SLEEP
- to set the PMIC state to sleep.
- - MAX77620_FPS_INACTIVE_STATE_LOW_POWER
- to set the PMIC state to low
- power.
- Absence of this property or other value
- will not change device state when FPS
- event get cleared.
-
-Here supported time periods by device in microseconds are as follows:
-MAX77620 supports 40, 80, 160, 320, 640, 1280, 2560 and 5120 microseconds.
-MAX20024 supports 20, 40, 80, 160, 320, 640, 1280 and 2540 microseconds.
-MAX77663 supports 20, 40, 80, 160, 320, 640, 1280 and 2540 microseconds.
-
--maxim,power-ok-control: configure map power ok bit
- 1: Enables POK(Power OK) to control nRST_IO and GPIO1
- POK function.
- 0: Disables POK control.
- if property missing, do not configure MPOK bit.
- If POK mapping is enabled for GPIO1/nRST_IO then,
- GPIO1/nRST_IO pins are HIGH only if all rails
- that have POK control enabled are HIGH.
- If any of the rails goes down(which are enabled for POK
- control) then, GPIO1/nRST_IO goes LOW.
- this property is valid for max20024 only.
-
-For DT binding details of different sub modules like GPIO, pincontrol,
-regulator, power, please refer respective device-tree binding document
-under their respective sub-system directories.

+ The Flexible Power Sequencer (FPS) allows each regulator to power up

+ power on independently or among a group of other regulators with an

+ and GPIO3 can be programmed to be part of a sequence allowing external
+ regulators to be sequenced along with internal regulators. 32KHz clock
+ can be programmed to be part of a sequence.
+
+ The flexible sequencing structure consists of two hardware enable inputs
+ (EN0, EN1), and 3 master sequencing timers called FPS0, FPS1 and FPS2.
+ Each master sequencing timer is programmable through its configuration
+ register to have a hardware enable source (EN1 or EN2) or a software enable
+ source (SW). When enabled/disabled, the master sequencing timer generates
+ eight sequencing events on different time periods called slots. The time
+ period between each event is programmable within the configuration register.
+ Each regulator, GPIO1, GPIO2, GPIO3, and 32KHz clock has a flexible power
+ sequence slave register which allows its enable source to be specified as
+ a flexible power sequencer timer or a software bit. When a FPS source of
+ regulators, GPIOs and clocks specifies the enable source to be a flexible
+ power sequencer, the power up and power down delays can be specified in
+ the regulators, GPIOs and clocks flexible power sequencer configuration
+ registers.
+
+ When FPS event cleared (set to LOW), regulators, GPIOs and 32KHz clock
+ are set into following state at the sequencing event that corresponds
+ to its flexible sequencer configuration register.
+
+ Sleep state: In this state, regulators, GPIOs and 32KHz clock get disabled
+ at the sequencing event.
+ Global Low Power Mode (GLPM): In this state, regulators are set in low
+ power mode at the sequencing event.
+
+ The configuration parameters of FPS is provided through sub-node "fps"
+ and their child for FPS specific. The child node name for FPS are "fps0",
+ "fps1", and "fps2" for FPS0, FPS1 and FPS2 respectively.
+
+ The FPS configurations like FPS source, power up and power down slots for
+ regulators, GPIOs and 32kHz clocks are provided in their respective
+ configuration nodes which is explained in respective sub-system DT

+
+ There is need for different FPS configuration parameters based on system
+ state like when system state changed from active to suspend or active to

This is odd interrupt. It's I2C device, so how can it be GIC?

Document an optional second I2C address for the MAX77663 PMIC's RTC
device, to be used if the MAX77663 RTC is located at a non-default I2C
address.

Convert RTC I2C device creation from devm_i2c_new_dummy_device() to
i2c_new_ancillary_device() to enable the use of a device tree-specified
RTC address instead of a hardcoded value. If the device tree does not
provide an address, use hardcoded values as a fallback.
This addresses an issue with the MAX77663 PMIC, which can have the RTC at
different I2C positions (either 0x48, like the MAX77714, or 0x68, like
the MAX77620). The MAX77620 value is used as the default. The I2C position
of the MAX77663 is factory-set and cannot be detected from the chip
itself.
