Description

RaspberryPi Pico core supply regurator

Properties

Properties not inherited from the base binding file.

Name

Type

Details

regulator-min-microvolt

int

smallest voltage consumers may set

regulator-max-microvolt

int

largest voltage consumers may set

regulator-always-on

boolean

boolean, regulator should never be disabled

regulator-boot-on

boolean

bootloader/firmware enabled regulator.
It's expected that this regulator was left on by the bootloader.
If the bootloader didn't leave it on then OS should turn it on
at boot but shouldn't prevent it from being turned off later.
This property is intended to only be used for regulators where
software cannot read the state of the regulator.

regulator-initial-mode

int

Initial operating mode. The set of possible operating modes depends on the
capabilities of every hardware so each device binding documentation
explains which values the regulator supports.

regulator-allowed-modes

array

List of operating modes that software is allowed to configure for the
regulator at run-time. Elements may be specified in any order. The set of
possible operating modes depends on the capabilities of every hardware so
each device binding document explains which values the regulator supports.

raspberrypi,brown-out-detection

boolean

Enable brown-out detection

raspberrypi,brown-out-threshold

int

Reset if the core voltage drops below this threshold for a particular time
(determined by the 'brown-out detection assertion delay').
