| $ref: /schemas/types.yaml#/definitions/flag |
| description: | |
| Boolean, if present disable all unused switch regulators to save power |
| consumption. 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. |
| Use this option if the SoC should be powered off by external power management |
| IC (PMIC) on PMIC_STBY_REQ signal. |
| As opposite to PMIC_STBY_REQ boards can implement PMIC_ON_REQ signal. |
