Attention, ensure that all important regulators (e.g. DDR ref, DDR supply) has set the "regulator-always-on" property. If not present, the switched regulators are always on and can't be disabled. This binding is a workaround to keep backward compatibility with old dtb's which rely on the fact that the switched regulators are always on and don't mark them explicit as "regulator-always-on". fsl,pmic-stby-poweroff: $ref: /schemas/types.yaml#/definitions/flag description: | if present, configure the PMIC to shutdown all power rails when PMIC_STBY_REQ line is asserted during the power off sequence.
