title: Richtek RT5133 PMIC Regulator
maintainers:
- ShihChia Chang <jeff_chang@richtek.com>
description:
The RT5133 is an integrated Power Management IC for portable devices,
featuring 8 LDOs and 3 GPOs. It allows programmable output voltages,
soft-start times, and protections via I2C. GPO operation depends on LDO1
voltage.

richtek,oc-shutdown-all:
type: boolean
description:
Controls the behavior when any LDO (Low Dropout Regulator) enters an
Over Current state.
If set to true, all LDO channels will be shut down.
If set to false, only the affected LDO channel will shut down itself.

type: boolean
description:
Controls the behavior when any LDO enters a Power Good Bad state.
If set to true, all LDO channels will be shut down.
If set to false, only the affected LDO channel will shut down itself.

description:
Properties for the base regulator, which is the top-level supply for
LDO1 to LDO6. It functions merely as an on/off switch rather than
regulating voltages. If none of LDO1 to LDO6 are in use, switching
off the base will reduce the quiescent current.
