43 $ref: /schemas/types.yaml#/definitions/flag
44 description: |
45 Boolean, if present disable all unused switch regulators to save power
46 consumption. Attention, ensure that all important regulators
47 (e.g. DDR ref, DDR supply) has set the "regulator-always-on" property.
48 If not present, the switched regulators are always on and can't be
49 disabled. This binding is a workaround to keep backward compatibility
50 with old dtb's which rely on the fact that the switched regulators are
51 always on and don't mark them explicit as "regulator-always-on".

53 fsl,pmic-stby-poweroff:
54 $ref: /schemas/types.yaml#/definitions/flag
55 description: |
56 if present, configure the PMIC to shutdown all
57 power rails when PMIC_STBY_REQ line is asserted during the power off sequence.
58 Use this option if the SoC should be powered off by external power management
59 IC (PMIC) on PMIC_STBY_REQ signal.
60 As opposite to PMIC_STBY_REQ boards can implement PMIC_ON_REQ signal.
