+Hisilicon Hi655x Power Management Integrated Circuit (PMIC)

+MAX77620 Power management IC from Maxim Semiconductor.
+
+Required properties:
+-------------------
+- compatible: Must be one of

+ "maxim,max20024".
+- reg: I2C device address.
+
+Optional properties:
+-------------------

+- interrupt-controller: Marks the device node as an interrupt controller.
+- #interrupt-cells: is <2> and their usage is compliant to the 2 cells

+ IRQ numbers for different interrupt source of MAX77620

+
+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.
+
+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.
+
+Example:
+--------
+#include
+
+max77620@3c {
+ compatible = "maxim,max77620";
+ reg = <0x3c>;
+
+ interrupt-parent = <&intc>;
+ interrupts = <0 86 IRQ_TYPE_NONE>;
+
+ interrupt-controller;
+ #interrupt-cells = <2>;
+
+ fps {
+ fps0 {
+ maxim,shutdown-fps-time-period-us = <1280>;
+ maxim,fps-event-source = ;
+ };
+
+ fps1 {
+ maxim,shutdown-fps-time-period-us = <1280>;
+ maxim,fps-event-source = ;
+ };
+
+ fps2 {
