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
|
||||

|
||||
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).

Thermal driver for MAX77620 Power management IC from Maxim Semiconductor.
|
||||
|
||||
Maxim Semiconductor MAX77620 supports alarm interrupts when its
|
||||
die temperature crosses 120C and 140C. These threshold temperatures
|
||||
are not configurable. Device does not provide the real temperature
|
||||
of die other than just indicating whether temperature is above or
|
||||
below threshold level.
|
||||
|
||||
Required properties:
|
||||
-------------------
|
||||
#thermal-sensor-cells: For more details, please refer to
|
||||
<devicetree/bindings/thermal/thermal-sensor.yaml>
|
||||
The value must be 0.
|
||||
|
||||
For more details, please refer generic thermal DT binding document
|
||||
<devicetree/bindings/thermal/thermal*.yaml>.
|
||||
|
||||
Please refer <devicetree/bindings/mfd/max77620.txt> for mfd DT binding
|
||||
document for the MAX77620.
