STMicroelectronics STPMIC1 Onkey
|
||||
|
||||
Required properties:
|
||||
|
||||
- compatible = "st,stpmic1-onkey";
|
||||
- interrupts: interrupt line to use
|
||||
- interrupt-names = "onkey-falling", "onkey-rising"
|
||||
onkey-falling: happens when onkey is pressed; IT_PONKEY_F of pmic
|
||||
onkey-rising: happens when onkey is released; IT_PONKEY_R of pmic
|
||||
|
||||
Optional properties:
|
||||
|
||||
- st,onkey-clear-cc-flag: onkey is able power on after an
|
||||
over-current shutdown event.
|
||||
- st,onkey-pu-inactive: onkey pull up is not active
|
||||
- power-off-time-sec: Duration in seconds which the key should be kept
|
||||
pressed for device to power off automatically (from 1 to 16 seconds).
|
||||
see See Documentation/devicetree/bindings/input/input.yaml
|
||||
|
||||
Example:
|
||||
|
||||
onkey {
|

compatible = "st,stpmic1-onkey";
|
||||
interrupt-parent = <&pmic>;
|

* STMicroelectronics STPMIC1 Power Management IC
|
||||
|
||||
Required properties:
|
||||
- compatible: : "st,stpmic1"
|
||||
- reg: : The I2C slave address for the STPMIC1 chip.
|
||||
- interrupts: : The interrupt line the device is connected to.
|
||||
- #interrupt-cells: : Should be 1.
|
||||
- interrupt-controller: : Marks the device node as an interrupt controller.
|
||||
Interrupt numbers are defined at
|
||||
dt-bindings/mfd/st,stpmic1.h.
|
||||
|
||||
STPMIC1 consists in a varied group of sub-devices.
|
||||
Each sub-device binding is be described in own documentation file.
|
||||
|
||||

STMicroelectronics STPMIC1 Voltage regulators
|
||||
|
||||
Regulator Nodes are optional depending on needs.
|
||||
|
||||
Available Regulators in STPMIC1 device are:
|
||||
- buck1 for Buck BUCK1
|
||||
- buck2 for Buck BUCK2
|
||||
- buck3 for Buck BUCK3
|
||||
- buck4 for Buck BUCK4
|
||||
- ldo1 for LDO LDO1
|
||||
- ldo2 for LDO LDO2
|
||||
- ldo3 for LDO LDO3
|
||||
- ldo4 for LDO LDO4
|
||||
- ldo5 for LDO LDO5
|
||||
- ldo6 for LDO LDO6
|
||||
- vref_ddr for LDO Vref DDR
|
||||
- boost for Buck BOOST
|
||||
- pwr_sw1 for VBUS_OTG switch
|
||||
- pwr_sw2 for SW_OUT switch
|
||||
|
||||
Switches are fixed voltage regulators with only enable/disable capability.
|
||||
|
||||
Optional properties:
|
||||
- st,mask-reset: mask reset for this regulator: the regulator configuration
|
||||
is maintained during pmic reset.
|
||||
- regulator-over-current-protection:
|
||||
if set, all regulators are switched off in case of over-current detection
|
||||
on this regulator,
|
||||
if not set, the driver only sends an over-current event.
|
||||
- interrupts: index of current limit detection interrupt
|
||||
- <regulator>-supply: phandle to the parent supply/regulator node
|
||||
each regulator supply can be described except vref_ddr.
|
||||
- regulator-active-discharge: can be used on pwr_sw1 and pwr_sw2.
|
||||
|
||||
Example:
|
||||
regulators {
|
||||
compatible = "st,stpmic1-regulators";
