-=======================================
-
-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
